OCR A Level Biology Past Papers, Mark Schemes and Examiners' Reports

Every OCR A Level Biology A (H420) and AS (H020) paper since the specification began, with the mark scheme and examiners' report beside each one. Use the switch to choose A level or AS. On a phone, tap a series to open it.

How to get the most from a paper

  1. Do it timed, in one sitting, with no notes.
  2. Mark it yourself with the mark scheme. Be strict: if your wording isn't on the scheme, don't give yourself the mark.
  3. For every question you dropped marks on, read what the examiners' report says about it. That is where you find out what the examiners actually wanted.

The MCQ quiz links turn each paper's multiple-choice section into a self-marking quiz.
