May/June session (primary)

The exact dates vary each year, but Biology papers are typically scheduled across late April to mid-June. Your school will confirm specific dates. Papers are usually spread over 1–3 weeks:

  • Paper 1/2 (Multiple choice): early–mid May
  • Paper 3/4 (Structured questions): mid–late May
  • Paper 5/6 (Practical/Alternative to practical): timing varies by school

Registration deadline: typically February. Results: usually mid-August.

October/November session

Available for retakes or schools with January-start academic years. Papers are scheduled across October to November. Results: usually mid-January.

Planning your revision

Work backwards from your exam dates. Allow at least 8 weeks of dedicated revision before the first paper. The final 2 weeks should focus on past papers and exam technique, not learning new content.
