Choose a small, relevant set
Choose questions that match the topic and level you are studying. Check the source with your teacher or tutor, especially when preparing for a particular curriculum. A random collection of difficult questions can hide the specific skill you need to practise.
Start with a short set you can review properly. Attempt it before reading the solutions, and keep your working even when you are unsure. An unfinished method gives your tutor more information than a blank page.
Name the reason for each mistake
After checking your answers, sort errors by cause: missing knowledge, an incorrect method, a calculation slip or a misunderstood instruction. If you cannot identify the cause, write down the exact step where you became uncertain.
Create a simple error log with four columns: question, what went wrong, correction and retry date. For example: ‘Expanded brackets incorrectly; multiplied the first term only; multiply every term; retry on Thursday.’ Avoid labels such as ‘careless’ that do not explain what to change.
Retry without the solution beside you
Close the answer sheet and work through the missed question again. Explain why each step is appropriate. Later, try a different question that uses the same idea to check whether you learned the method or remembered the answer.
If the same error returns, bring both attempts to a lesson. Ask for help with the underlying concept before adding more questions of the same difficulty.
Add timing when the method is clearer
Once you can explain your approach, practise completing a small set within an agreed time. Record unanswered questions separately from incorrect ones: running out of time and misunderstanding a topic need different responses.
Use the results to choose the next practice task. This guide describes a study process, not an exam board’s current format or rules; check official instructions for your actual examination.
