IGCSE Biology MCQ revision guide

What you're actually sitting

IGCSE Biology (0610) multiple choice is two 40-question papers, Paper 1 (Core) and Paper 2 (Extended), at 45 minutes each. It's the friendliest of the big sciences in our data, averaging 87.4% and the quickest to finish at about 16 minutes.

Where students lose marks

• Definitions and command words. Biology rewards precise vocabulary; vague paraphrases lose marks.
• Diagram and process questions. Labelled structures, transport processes, and cycles need to be recalled exactly.
• Data interpretation. Reading tables and graphs carefully separates the high scorers.

A practice plan that works

The danger in Biology is complacency: because most students score in the high 80s, dropped marks cost you more relative to everyone else. Use the hardest-papers list to find the few papers that genuinely challenge people, and treat every wrong MCQ as a missing definition or misread diagram to fix, not a fluke.
