How to use these papers
Almost every free-response question is built around data you have not seen, so the useful practice is not recalling content but reading an unfamiliar graph quickly. Time yourself on that step alone: give yourself two minutes to say what a released question's figure shows before reading the prompt.
Mark yourself hard on the verbs. "Describe the trend" and "explain the trend" are different tasks with different rubrics, and answering the wrong one is the single commonest way to lose marks you knew the biology for.
Do the statistics parts even though they look peripheral. Chi-square and standard error appear regularly, they are procedural, and they are among the most reliable marks available.
