Build a simple pacing plan before you answer
Before you start writing, spend a short amount of time mapping the paper. Note the total time, the sections, the marks and any compulsory questions. Then divide the time in a way that matches the marks and answer types. A rough minutes-per-mark check can help, but it is only a guide: a long essay, a source question and a short-answer section may all need different handling. A practical plan is: reading time, first pass through the questions, reserve time for your highest-value answers, and a final check. If the paper has no formal reading time, build your own quick scan into the opening minutes.
Scan the paper
Check the sections, instructions and question choices before committing to an answer order.
Use marks as a guide
Spend longer on higher-value answers, but adapt for answer type and subject.
Protect checking time
Leave a realistic buffer for the work you most need to check.
