To self-assess your performance, use this question paper alongside the corresponding mark scheme (5070_s26_ms_21). Attempt the entire paper under timed conditions before opening the mark scheme — this trains both your subject knowledge and exam technique. Mark each question and record whether marks were lost due to knowledge gaps, method errors, or careless mistakes.
The most effective way to use this Chemistry question paper is to simulate real exam conditions: set a timer for the full duration, work without notes, and write your answers on separate paper. After finishing, mark yourself using the official mark scheme — do not check answers during the paper. This builds exam stamina and reveals your genuine readiness. Repeat this process across 3–5 sessions to identify recurring weak topics in Chemistry (5070).
