Please attempt each question before looking at the worked solutions. Maths is learnt best by doing rather than reading.

​

Instead of doing the whole paper then marking your work, it can be more effective to:

​

1. Attempt one question
    

2. If you get an answer, look at the official mark scheme to see if you are correct
    

3. Use these worked solutions if you were incorrect or were unsure what to do to guide you in the correct way of doing it
    

4. Complete the question yourself
    

5. Proceed to the next question
    

This ensures that each question is fresh in your mind, and you get instant feedback. Waiting until the end of the paper for you or someone else to mark your work means that you may have forgotten your thought processes by the time you get feedback.

​

Please note that these worked solutions have neither been provided nor approved by the exam boards and may not necessarily constitute the only possible solutions. Please refer to the original mark schemes for full guidance.
