How to practise Solutions PYQs
- Start with the concepts at the top of the table. They have come back the most.
- Solve one year’s Solutions questions from the official PDF against the clock, then check the answer listed below.
- Log every miss as a concept gap, a calculation slip or a misread. Each needs a different fix.
- Once a concept is clean in two papers, move to the next. Then sit a full paper from the year pages.
