This document contains 50 AQA A-Level
Biology exam-style questions with clear
answers designed to help students revise key
topics and prepare for assessments. The
questions cover important areas of the A-Level
Biology specification from AQA, including
biological molecules, cells, genetics,
ecosystems, and gene expression.
Each question is followed by a concise answer
to help reinforce understanding and improve
exam technique. This resource is useful for
self-testing, revision before exams, and
practising how to answer typical A-Level
Biology questions.
