What Cambridge examiners say about Computer Science
Verbatim quotes from 2 official Cambridge examiner reports (2023). Every quote is attributable to a specific paper and session — these are the things Cambridge markers flag year after year.
Generic descriptions of sensor-based systems instead of…
Very few candidates were able to provide a detailed, technical and accurate response for this question. Many candidates gave a generic description of a system that uses sensors and microprocessors.
Not understanding library routines like DIV and ROUND
Few candidates understood the purpose of DIV and ROUND. Candidates who understood the library routines were able to give a suitable example.
Unable to describe sound representation
Few candidates were able to state what is meant by the sample rate and resolution. Some candidates tried to describe the sample resolution in relation to an image.
Most Common Mistakes — Computer Science (2210)
Based on analysis of 2 official Cambridge examiner reports (2023). Avoid these errors to maximise your marks.
Generic descriptions of sensor-based systems instead of applying to the given context
Paper 1 · Widespread across Paper 1 variants, 2023
Not understanding library routines like DIV and ROUND
Paper 2 · Common in Paper 2, 2023
Unable to describe sound representation — confusing sample rate/resolution with image concepts
Paper 1 · Common in Paper 1, 2023
Describing benefits of compilers instead of how they operate
Paper 1 · Common in Paper 1, 2023
Using programming language syntax instead of pseudocode
Paper 2 · Seen across Paper 2 variants, 2023
Topics Students Struggle With Most
Sound representation (sample rate and resolution)
Few candidates could define sample rate and resolution for sound. Some confused sound resolution with image resolution, showing weak understanding of how sound is stored digitally.
Paper 1
Compiler operation and error reporting
Few candidates could technically describe how a compiler works. Most only stated it creates an executable file, and some described benefits rather than the compilation process.
Paper 1
Library routines (DIV, MOD, ROUND) and pseudocode string functions
Few candidates understood DIV and ROUND. Many used programming language syntax (e.g. Python's .upper()) instead of the syllabus pseudocode functions (UCASE).
Paper 2
Packet switching — full process description
Most candidates only mentioned data split into packets and different routes. Few described the complete process including headers, routing, and reassembly using sequence numbers.
Paper 1
Expert systems — role of the inference engine
Very few candidates could accurately describe the role of the inference engine. Candidates seemed to either know expert system components fully or not at all.
Paper 1
Benefits of low-level languages
Few candidates could give valid reasons for using a low-level language. Many incorrectly claimed it makes programs 'more secure from hackers' rather than citing direct hardware access or efficiency.
Paper 1
Brute-force attack process
Few candidates could provide an accurate description of how a brute-force attack is carried out beyond 'trying to guess a password'. The systematic, automated nature of the attack was poorly understood.
Paper 1
Lossless compression of text files
Some candidates confused lossless compression of text with image compression techniques. Others described lossy compression methods instead, showing weak understanding of how text is compressed without data loss.
Paper 1
Verification vs validation — distinct concepts
A significant number of candidates incorrectly selected verification as 'making sure that a value entered is correct'. Verification confirms data matches its source/original input (double entry, visual check); validation confirms data is reasonable (range, length, format, type, presence checks).
Paper 2
Machine learning capabilities
Very few candidates were able to give an accurate explanation of what is meant by machine learning capabilities. Candidates would benefit from a greater understanding of how systems learn from data, refine algorithms, and adapt over time.
Paper 1
SQL queries with multiple conditions (AND in WHERE)
Some candidates did not use AND in the WHERE field when a query required multiple conditions, treating each condition as a separate query instead of combining them with a logical operator.
Paper 2
Flowchart construction — symbols, arrow-heads, decision-box labelling
Quite a few candidates did not use the correct flowchart symbols, drew lines instead of arrows, or had arrows that did not touch the connecting symbol. Decision boxes also need clearly labelled Yes/No paths.
Paper 2
Computer Science (2210) — Cambridge O Level Full Archive 2015–2026
This page contains all 226 available papers for Cambridge O Level Computer Science (2210) — 24 exam sessions from 2015 to 2026. Each session includes question papers, mark schemes, and where available, examiner reports and grade threshold documents. All files are free to download as PDF — no account required.
Cambridge O Level Computer Science (2210) is examined through multiple paper components. Question papers are available in two or three variants per session (v1, v2, v3) — each variant is sat in a different time zone but covers the same syllabus content and is equivalent in difficulty. The paper number in the filename indicates which component: for example, 2210_qp_12 is Paper 1, Variant 2.
Mark schemes for 2210 show the exact marking points accepted by Cambridge examiners. Many questions have multiple acceptable phrasings — look for 'accept', 'allow', and 'credit' in the mark scheme to understand the full range of valid responses. Examiner reports (where available) reveal the most common errors made by the cohort and what top-band answers looked like, making them essential reading before the actual exam.
The most effective way to use this archive is to attempt past papers under timed exam conditions, then analyse your mark scheme results by component. Track which paper components and question types you score lowest on — this tells you exactly where to focus revision. Grade threshold documents show the minimum mark needed for each grade in that specific session, which helps calibrate how your practice scores translate to actual grades.
