How to get the most out of these papers
Write the most recent Life Sciences paper first, in the full time, without notes. Then mark it with the memo and write down every question where you lost marks. Those questions show the topics to revise next. Once you have revised them, write an older paper and compare your marks. Doing one paper a week in the run-up to the exam is one of the most reliable ways to improve your Life Sciences results.
