About Biology (5090)

Biology (5090) — CAIE Full Archive 2002–2025

This page contains all 877 available papers for CAIE Biology (5090) — 51 exam sessions from 2002 to 2025. Each session includes question papers, mark schemes, and, where available, examiner reports and grade threshold documents. All files are free to download as PDF — no account required.

CAIE Biology (5090) builds the core concepts and skills students need to think clearly about this discipline. The syllabus blends factual knowledge with applied problem solving, so practice with real questions matters more than memorisation. Working through past papers regularly reveals the patterns examiners reward and the wording they expect in answers. Use the mark schemes and examiner reports together — they show not just the right answer but how to express it.

The most effective way to use this archive is to attempt past papers under timed exam conditions, then analyse your mark scheme results by component. Track which paper components and question types you score lowest on — this tells you exactly where to focus revision. Grade threshold documents show the minimum mark needed for each grade in that specific session, which helps calibrate how your practice scores translate to actual grades.
