What Are Assessment Objectives (AOs)?

Before we dive in, you need to understand how Edexcel actually marks your answers.

AO stands for Assessment Objective. Think of AOs as the different “skills” Edexcel tests you on in every single question. When an examiner marks your paper, they don't just give you a mark out of 12 based on how “good” your answer feels — they allocate specific marks to each AO separately.

For example, a 12-mark question might be split as: AO1 (2 marks) + AO2 (2 marks) + AO3 (2 marks) + AO4 (6 marks). If you write a perfect textbook answer but don't evaluate, you can only score 6 out of 12 — because the other 6 marks are specifically reserved for evaluation.

This is why understanding AOs matters: they tell you exactly what the examiner is looking for and how many marks each skill is worth. Here are the 3 AOs for this subject:

AO1

Knowledge and Understanding

31-33%

Recall and demonstrate knowledge of physics facts, concepts, definitions, and laws. Definitions must be word-perfect — omitting key qualifiers such as 'per unit', 'resultant', or 'very high' will lose the mark. Indicative-content questions reward clear, precise statements over vague recall.

AO2

Application of Knowledge and Understanding

41-43%

Apply physics to solve problems, interpret data, perform multi-stage calculations, and analyse experimental results. Always state the equation first, then substitute values with units. Show every unit conversion as a visible step. For 'deduce whether' questions, a clear numerical conclusion is mandatory.

AO3

Analysis, interpretation and evaluation of scientific information

25-27%

Demonstrate understanding of experimental design, uncertainty, and practical technique — predominantly through Paper 3 indirect practical questions. Candidates must distinguish between resolution, uncertainty, accuracy and precision; know how to combine percentage uncertainties; and express limitations specifically rather than generically.

The key takeaway: Most students lose marks not because they lack knowledge (AO1), but because they skip the higher-order skills — building chains of reasoning (AO2) and making supported judgements (AO3). Everything below shows you exactly how to hit each AO based on what Edexcel examiners have written in their reports.

Top Mistakes in A Level Physics 9PH0

The most common reasons students lose marks in A Level Physics 9PH0, cited directly from official Edexcel examiner reports across multiple sessions.

Omitting or forgetting units on final numerical answers

Flagged in all five examiner reports across all three papers · Affects: Paper 1, Paper 2, Paper 3

What examiners say

“In some calculation questions the final mark was not awarded due to a missing unit. This seemed to be more prevalent in this years' examination.”
— 9PH0 Paper 3, June 2023

“Remember that physical quantities have a magnitude and a unit and both must be given in answers to numerical questions.”
— 9PH0 Paper 2, June 2023

“In some calculation questions the final mark was not awarded due to a missing unit. This seemed to be more prevalent in this year's examination.”
— 9PH0 Paper 3, June 2024

How to fix this

After every calculation, check: magnitude written? unit written? For SI-prefixed answers, write the unit explicitly (e.g. 2.4 × 10⁻³ kg, not just 2.4 × 10⁻³). Note that 'show that' questions are the only exceptions where final units are not penalised — on all other calculation questions a missing unit costs the answer mark.

Free-body force diagrams — wrong direction, missing forces, or extra forces

Paper 1 June 2023, Paper 3 (regular feature) · Affects: Paper 1, Paper 3

What examiners say

“This free-body force diagram was only completed successfully by a minority of candidates.”
— 9PH0 Paper 1, June 2023

“Note that free-body force diagrams are not as straightforward as people think.”
— 9PH0 Paper 1, June 2023

“A number of candidates drew this force acting in the opposite direction, or to the right rather than upper left.”
— 9PH0 Paper 1, June 2023

How to fix this

List every object exerting a force on the body in question (gravity, normal contact, tension, friction, magnetic, etc.). Draw each arrow from the body outward. Label angle values numerically — do not rely on visual accuracy alone. The third force must create equilibrium: after drawing two forces, the third must close the vector triangle. Verify by checking the resultant is zero.

Calculator in wrong angle mode — degrees vs radians

Paper 2 June 2024 · Affects: Paper 2

What examiners say

“Check which mode the calculator is set to. In this case we need to use degrees, as the angle is expressed in degrees.”
— 9PH0 Paper 2, June 2024

“When carrying out calculations which involve performing sine or cosine functions with quantities in radians, always make sure the calculator is in radians mode.”
— 9PH0 Paper 2, June 2024

“MP2 was frequently not awarded when MP1 had been, due to not converting radians.”
— 9PH0 Paper 2, June 2024

How to fix this

Before every trigonometric calculation: check whether the given angle is in degrees or radians. Diffraction grating and most field problems use degrees. SHM (ω in rad s⁻¹) and circular motion use radians. Set the calculator mode before substituting. If using sin ωt in SHM, the answer will be in radians — do not convert to degrees halfway through.

Temperature not converted to kelvin in ideal gas and thermodynamics calculations

Paper 2 June 2023, Paper 2 June 2024, Paper 3 June 2024 · Affects: Paper 2, Paper 3

What examiners say

“A substantial minority of candidates were unable to complete the calculation correctly because they either used the stated temperatures without calculating a temperature change, or they used the temperature change of 4 K for the block as well as the water and the glass container. A few candidates went further astray by converting Celsius temperatures to kelvin.”
— 9PH0 Paper 2, June 2023

“Know that in calculations which involve ideal gases, temperature must be converted to K.”
— 9PH0 Paper 2, June 2024

“Before substituting convert Celsius temperatures to kelvin, unless a temperature difference is being calculated.”
— 9PH0 Paper 3, June 2024

How to fix this

Any equation containing T (absolute temperature) requires kelvin: pV = NkT, pV = nRT, ½m<c²> = 3/2 kT, Stefan-Boltzmann law. Add 273 (or 273.15) to convert. Exception: when calculating a temperature change ΔT, kelvin and Celsius differences are identical so no conversion is needed. Never convert a ΔT value by adding 273.

Applying suvat (kinematic) equations to SHM where acceleration is not constant

Paper 2 June 2024, Paper 3 June 2023 · Affects: Paper 2, Paper 3

What examiners say

“Some candidates had attempted to answer the question using kinematic equations of motion (suvat equations). As the acceleration is not constant, this method was not awarded any marks.”
— 9PH0 Paper 2, June 2024

“A minority of candidates didn't realise that they needed to use the graph to determine the period. Some candidates attempted to calculate speed using distance divided by time, or tried to use v = f l.”
— 9PH0 Paper 3, June 2023

How to fix this

SHM uses its own equation set: a = −ω²x, v = −Aω sin ωt, x = A cos ωt. For maximum velocity, sin ωt = 1 so vmax = Aω. Suvat equations (v = u + at etc.) apply only when acceleration is constant. In SHM, acceleration varies with displacement — suvat gives zero marks. For maximum speed use vmax = Aω, not v = d/t.

Confusion between resolution and uncertainty, and errors in combining percentage uncertainties

Paper 3 June 2023, Paper 3 June 2024 · Affects: Paper 3

What examiners say

“Some candidates struggled to use the terms 'resolution' and 'uncertainty' correctly, and there was general unfamiliarity with the process of combining uncertainties in sums and differences.”
— 9PH0 Paper 3, June 2023

“when measurements are added or subtracted in a calculation the uncertainty for each measurement is added to calculate the total uncertainty. when multiplying or dividing measurements, the total percentage uncertainty is calculated by adding together the percentage uncertainties for each measurement.”
— 9PH0 Paper 3, June 2023

“For MP2, many referred to uncertainty instead of percentage uncertainty. This was not sufficient for the mark to be awarded, as uncertainty stays the same, but percentage uncertainty is reduced.”
— 9PH0 Paper 3, June 2024

How to fix this

Resolution is a property of the instrument (smallest readable interval). Uncertainty for a single measurement is half the resolution. To combine: ADD absolute uncertainties for sums/differences. ADD percentage uncertainties for products/quotients. For powers, MULTIPLY the percentage uncertainty by the index (e.g. volume = length³ → %uncertainty in V = 3 × %uncertainty in length). Stacking objects increases the measured quantity and reduces percentage uncertainty — it does not change the absolute uncertainty.

Not paying attention to command words — answering 'describe' with an explanation and vice versa

Paper 3 June 2023, Paper 3 June 2024 · Affects: Paper 3

What examiners say

“There is still evidence that candidates are not paying sufficient attention to the command words used in the question. In a number of cases, questions requiring an explanation were answered with a description and vice versa by a proportion of candidates.”
— 9PH0 Paper 3, June 2023

“Pay attention to the command word – "explain" requires reasoning, unlike "describe".”
— 9PH0 Paper 3, June 2024

“Many responses were descriptions rather than explanations of the shape of the graph.”
— 9PH0 Paper 3, June 2024

How to fix this

Describe = state what happens or what is observed. No reasoning required. Explain = state what happens AND give the physical reason why. Justify = give evidence or logic for a claim. Deduce = use provided data or derivation to reach a conclusion. When the command word is 'explain', include a causal chain — for example: increasing V → increasing I → higher temperature → higher resistance (not just 'as voltage increases, resistance increases').

Misreading or misapplying the redshift equation — swapping emitted and detected wavelengths

Paper 2 June 2023 · Affects: Paper 2

What examiners say

“a majority of those who did incorrectly used the wavelength of the detected radiation as the denominator when they should have used the wavelength of the emitted radiation as the denominator and the difference between the wavelengths as the numerator.”
— 9PH0 Paper 2, June 2023

“Quite a few candidates who correctly substituted into the red shift equation made an algebraic error in their final rearrangement, subtracting λ from 14λ rather than adding it.”
— 9PH0 Paper 2, June 2023

How to fix this

Redshift formula: z = Δλ / λ₀ where λ₀ is the emitted (laboratory) wavelength and Δλ = λ_observed − λ_emitted. The denominator is always the emitted wavelength. A redshift (moving away) increases observed wavelength: λ_observed = λ₀ + Δλ (add). A blueshift (moving towards) decreases it. When rearranging, be careful whether to add or subtract Δλ. Write every algebraic step explicitly before substituting numbers.

What A Level Physics 9PH0 Examiners Reward

Patterns that consistently earn high marks in A Level Physics 9PH0, based on Edexcel examiner report commentary on top-scoring answers.

State the equation before substituting numerical values

Across all five reports, marks are awarded for stating a correct equation even when the subsequent calculation contains an error. Writing the equation first earns a 'use of' mark. Candidates who skip straight to numbers risk scoring zero if the answer is wrong.

Source: 9PH0 Paper 1, June 2023; 9PH0 Paper 3, June 2023

Substitute values into the equation before rearranging

Rearranging first and then substituting is a common route to algebraic errors. The examiner reports repeatedly commend candidates who substitute numbers into the correct equation and then solve, rather than pre-rearranging. A 'use of' mark requires a correct equation with values substituted.

Source: 9PH0 Paper 3, June 2023

Use vector diagrams for momentum conservation questions

Consider that momentum conservation questions can be solved elegantly using a labelled, vector diagram. This method is usually quicker than a calculation. Candidates who drew correctly labelled vector diagrams with arrows scored full marks even when a pure arithmetic approach failed.

Source: 9PH0 Paper 1, June 2023

For linkage (extended writing) questions: plan first, sequence ideas logically

Plan your response to an extended open-response question so that you are clear which points you are going to make before you start writing your response. Two marks in a 6-mark linkage question are specifically for logical sequencing of ideas — these are only awarded if conclusions are explicitly linked to evidence.

Source: 9PH0 Paper 3, June 2023

When asked to 'deduce whether' or 'assess', always give an explicit numerical conclusion

Where you are asked to make a judgement or to come to a conclusion by command words such as 'determine whether' or 'deduce whether', you must make a clear statement, including any values being compared. If it is a numerical comparison, you must show all steps in your calculation.

Source: 9PH0 Paper 2, June 2023

In 'show that' questions, give final answer to at least one more significant figure than the quoted value

In a 'show that' question you must give your final answer to at least one more significant figure than the value quoted in the question. Reaching exactly the quoted value without extra sf suggests the calculation was worked backwards and may not earn full credit.

A Level Physics 9PH0 Answer Frameworks

Structured approaches for each A Level Physics 9PH0 question type, derived from Edexcel mark scheme requirements.

Multi-stage calculation (3–6 marks)

4–8 minutes

Structure

Write equation → convert units → substitute all values → solve → state answer with unit to appropriate sf

•State the equation in symbols first — this earns a mark even if the arithmetic fails
•Substitute numerical values before algebraically rearranging the equation
•Keep at least 4 significant figures in intermediate steps; round only at the final answer
•Never omit the unit on the final answer — it costs the last mark
•For 'show that' questions, give your answer to one more sf than the printed value

Linkage / extended writing (6 marks)

8–10 minutes

Structure

Plan → write 4 content points in a logical chain → explicitly connect evidence to conclusions

•Plan the sequence of ideas before writing — 2 of the 6 marks are for logical sequencing
•In nuclear/particle questions: connect each degree of deflection to a specific conclusion about structure
•Do not describe what is not asked — extraneous detail wastes time and does not prevent marks, but concise answers score the same and are faster
•If a diagram is provided, annotating it clearly can substitute for prose marks

Indirect practical skills — uncertainty questions (2–4 marks)

3–5 minutes

Structure

State resolution → calculate absolute uncertainty → calculate percentage uncertainty → state the combination rule → apply it

•Distinguish resolution (instrument property) from uncertainty (measurement property)
•For sums/differences: add absolute uncertainties. For products/quotients: add percentage uncertainties
•Stacking objects reduces percentage uncertainty because the measurement increases while the absolute uncertainty stays the same
•Always use percentage uncertainty (not uncertainty) when discussing improvement — uncertainty stays constant

Indicative content / describe-the-physics questions (3–5 marks)

3–6 minutes

Structure

Check command word → give the number of distinct points matching the mark allocation → use precise scientific language

•Count the marks: each mark point requires a separate, distinct statement
•Avoid vague pronouns — name the specific object, quantity, or particle
•For 'describe' questions: do not explain. For 'explain' questions: include a causal chain (A happens because B, which causes C)
•For radioactive decay definitions, say exactly which nucleus will decay next and when — not just 'cannot be predicted'

A Level Physics 9PH0 Command Words Decoded

Each command word in A Level Physics 9PH0 is a scoring instruction. Understanding what Edexcel examiners expect is critical to earning full marks.

state1 mark

Give a brief factual answer — a value, term, or short statement. No working or explanation required.

Common mistake

Writing a long explanation when only a single word or phrase is needed. Candidates who write 'it cannot be predicted' lose the mark because 'it' is too vague — state specifically which nucleus or which event.

describe1–3 marks

State what happens or what is observed. Do not explain why.

Common mistake

Giving a causal explanation instead of an observation. Many Paper 3 responses described rather than explained the shape of a graph and scored zero.

explain2–4 marks

State what happens AND give the physical reason why, using a logical causal chain.

Common mistake

Describing observations without providing the underlying physics. For a V-I graph of a filament lamp, 'resistance increases' is a description; 'increasing current heats the filament, raising its temperature, which increases resistance' is an explanation.

calculate2–5 marks

Find a numerical value. Show the equation, substitution with units, and final answer with unit.

Common mistake

Omitting the final unit, rearranging before substituting (leading to algebraic errors), or using an incorrect formula. Without full substitution into a correct equation there is no 'use of' mark.

derive2–4 marks

Show, step by step, how a given equation follows from first principles or from stated equations.

Common mistake

Subsuming multiple steps into one line. Each fundamental equation must be stated separately before being combined. Skipping v = d/t in a derivation, for example, costs the mark even if the result is correct.

deduce1–3 marks

Reach a conclusion from given data or from a derivation. A clear final statement is mandatory.

Common mistake

Performing the calculation correctly but omitting the conclusion. The final mark is only awarded for an explicit comparison or judgment, not just a numerical answer.

suggest1–2 marks

Apply physics knowledge to an unfamiliar or open-ended situation. More than one answer may gain credit.

Common mistake

Giving a vague general answer instead of a specific, physics-based suggestion. 'Take more measurements' does not qualify; 'stack multiple washers to increase the length being measured and reduce percentage uncertainty' does.

justify1–2 marks

Support a claim or choice with quantitative or logical physics evidence.

Common mistake

Asserting a conclusion without the supporting evidence. In practical questions, a numerical comparison or reference to a calculated range is usually required.

A Level Physics 9PH0 Diagram Checklist

Incorrect diagrams in A Level Physics 9PH0 are flagged in every Edexcel examiner report. Use this checklist before every practice and in the exam.

Free-body force diagram

Draw all forces acting on the body: weight (straight down from centre of mass), normal contact (perpendicular to surface), tension (along cord/rod), friction (opposing relative motion), any electromagnetic force. Each arrow must show correct direction and magnitude label. For a body in equilibrium, forces must form a closed vector triangle.

Common error: Drawing the force from the connected rod in the wrong direction (e.g. to the right instead of upper-left). Adding extra forces from the same object. Not including the perpendicular component when a force acts at an angle (e.g. Y sin 35° rather than Y alone). Most candidates scored only a minority of free-body marks.

Vector diagram for momentum conservation

Draw one arrow for every momentum vector (before and after collision). For two-object collision: four arrows total. All arrows must be labelled with the quantity they represent and have the arrow direction shown. The 'before' and 'after' vectors must start at the same point for a valid diagram.

Common error: Drawing a single unlabelled triangle and reading a number from it. Failing to recognise that both bat and ball are moving before and after the collision — only drawing vectors for one object. Not starting vector lines at the correct origin point.

Ray diagram for diverging (eyepiece) lens

Axes: Principal axis × N/A

For an eyepiece in a refracting telescope: the intermediate image acts as a virtual object to the left of the diverging lens. Rays must travel towards the eye (to the right). Draw a ray through the optical centre undeviated, and a ray parallel to the principal axis refracted as if diverging from the focal point. The virtual image is upright and on the same side as the object for this lens.

Common error: Drawing rays going away from the eye (to the right) when the eye is to the right. Treating the diverging lens as converging. The most common response — drawing the correct converging-lens diagram for a real image — earns only the mark for the ray through the optical centre.

Blackbody radiation curve (intensity vs wavelength)

Axes: Wavelength / nm × Intensity (arbitrary units)

Peak at wavelength calculated from Wien's law (λ_max T = 2.898 × 10⁻³ m K). The curve is asymmetric: rises steeply from zero at short wavelengths (left), peaks, then falls more gradually at longer wavelengths (right). The right-hand tail must be wider than the left-hand rise.

Common error: Starting the curve from non-zero intensity at wavelength zero. Drawing the curve wider on the left (short-wavelength) side than the right — the correct curve has a steeper short-wavelength rise and a longer tail on the long-wavelength side. Only around 10% of candidates drew the full curve correctly.

Log-log or ln-ln linearised graph

Axes: log(T/K) or ln(T/K) — note: log of dimensionless ratio × log(V/V) or ln(V/V) — note: log of dimensionless ratio

Straight line of best fit. Gradient triangle must span at least half the drawn line. Axes labelled as log(quantity/unit), not 'log V / V' (which is ambiguous — is it the log divided by V, or the log of V/V?).

Common error: Writing axis labels as 'log V / V' instead of 'log (V/V)'. Choosing awkward scales (intervals of 2.5) that are hard to read. Forcing the line through a false origin. Using a gradient triangle smaller than half the line length. Axes labels were incorrectly written in almost half of responses.

v-t graph and a-x graph for SHM

Axes: Time t / s (for v-t) or Displacement x / m (for a-x) × Velocity v / m s⁻¹ (for v-t) or Acceleration a / m s⁻² (for a-x)

v-t graph: sinusoidal; maximum speed at x = 0 (equilibrium). a-x graph: straight line through origin with NEGATIVE gradient (a = −ω²x). At maximum positive displacement, acceleration is maximum and negative.

Common error: Treating SHM velocity as constant and drawing a straight v-t line. Drawing an a-x curve rather than a straight line. A positive gradient on the a-x graph means acceleration is in the same direction as displacement — this violates the definition of SHM.

⚠️

Topics Students Struggle With Most In A Level Physics 9PH0

These A Level Physics 9PH0 topics consistently produce the lowest scores. Prioritise these in your revision.

Free-body force diagrams — direction, completeness, and equilibrium condition

This free-body force diagram was only completed successfully by a minority of candidates. Common errors included drawing a force in the wrong direction and failing to recognise that the third force must produce equilibrium.

Affects: Paper 1

Vector diagrams for momentum — labelling both objects before and after

Only a minority of candidates realised that there were two objects moving before the collision and the same two objects were moving after the collision. The most common answer was to draw a single line to represent two separate vectors.

Affects: Paper 1

Internal resistance and terminal potential difference

Most candidates failed to realise that although the potential difference across the bulb would be a little less than 12 V, the resistance of the bulb would still be its working resistance. Many also confused terminal p.d. with e.m.f., or used incorrect p.d. values.

Affects: Paper 3

Combining uncertainties in products, quotients, and powers

Most candidates seemed to be unaware that when measurements are added or subtracted in a calculation the uncertainty for each measurement is added to calculate the total uncertainty. These rules are explicitly stated in Appendix 10 of the specification.

Affects: Paper 3

Conditions for nuclear fusion — precise description vs explanation confusion

A fairly common reason for not scoring was that candidates stated 'high temperature' rather than 'very high temperature'. Candidates should remind themselves of the requirements indicated by different command words, such as 'describe' versus 'explain'.

Affects: Paper 2

Definitions of 'random' and 'spontaneous' radioactive decay

The majority of responses scored 0 or 1 mark only. MP2 was frequently not awarded due to candidates saying 'it cannot be predicted' without clarifying what 'it' was, eg when the next nuclei will decay.

Affects: Paper 2

Standing waves — amplitude, position of antinodes, and superposition terminology

MP2 was sometimes not awarded as the candidate had used the term 'superimpose', which is not correct. MP4 was frequently not scored for not referencing the location of the antinode/nodes. Many used 'superimpose' (incorrect) instead of 'superpose' (correct).

Affects: Paper 2

Parallel circuits and the effect of adding a branch on terminal p.d.

It is clear from the responses seen that candidates struggle with the concepts involved in parallel circuits, with most candidates having a vague recollection of current splitting at a junction from their GCSE knowledge which they then erroneously applied.

Affects: Paper 3

Frequently Asked Questions

How is Edexcel A Level Physics (9PH0) assessed?

9PH0 consists of three written papers, all taken at the end of Year 13. Paper 1 (Advanced Physics I, 90 marks, 1h 45m) covers mechanics, electric circuits, and nuclear physics. Paper 2 (Advanced Physics II, 90 marks, 1h 45m) covers waves, thermodynamics, radiation, and space physics. Paper 3 (General and Practical Principles in Physics, 120 marks, 2h 30m) is a synoptic paper testing content across the whole specification, including indirect practical skills and linkage questions. There is no coursework component — practical skills are assessed entirely through Paper 3.

How was this exam guide built?

This guide was built by analysing 5 official Pearson Edexcel examiners' reports (2023–2024) for 9PH0: Paper 1 June 2023, Paper 2 June 2023, Paper 2 June 2024, Paper 3 June 2023, and Paper 3 June 2024 (the Paper 1 June 2024 report was excluded due to a Pearson PDF font-encoding issue). Every mistake pattern, scoring tip, and command-word definition is directly sourced and quoted from these documents. No third-party summaries or unofficial notes were used.

How is the AS Physics qualification (8PH0) related to 9PH0?

8PH0 is the standalone AS Level qualification; 9PH0 is the full A Level. The two are co-teachable but separately certificated. 8PH0 covers a subset of the 9PH0 content (roughly the Year 12 material) and is assessed by 2 AS papers rather than the 3 A-Level papers. Candidates studying towards 9PH0 do not need to enter for 8PH0, but AS-level past papers are a useful source of practice for Paper 1 and Paper 2 topics. The 9PH0 qualification code appears on all full A Level examiner reports; reports labelled 8PH0 relate to the AS qualification only.

What's on the Edexcel A Level Physics formulae sheet, and what isn't?

Pearson provides a Data, Formulae and Relationships Booklet in all 9PH0 exams containing fundamental constants, equations from each topic area, and a mathematical formulae section. However, the booklet does NOT include everything — the circumference of a circle and the volume of a cylinder must be remembered, as must standard definitions (threshold frequency, photon, etc.). The examiner reports note that candidates should 'remember that physics formulae are provided in the exam, the formulae for the circumference of a circle and volume of a cylinder must be remembered'. Always check whether a needed formula is in the booklet before the exam, and memorise the ones that are absent.

How are the 16 Core Practicals tested in 9PH0?

The 16 Core Practicals are not assessed as a written coursework component — instead, Paper 3 includes indirect practical skills questions that draw on the experiences and understanding gained through those practicals. Questions may ask candidates to evaluate a described method, identify sources of error, suggest improvements, or apply uncertainty analysis to a given data set. Familiarity with the actual apparatus, measurements, and typical errors from each core practical is therefore essential. The examiner reports note that 'candidates disadvantaged themselves by not using suitably precise language' in practical questions, and that 'candidates should be using all the information that they are given in the question' — suggesting that full practical engagement during teaching is expected.
