AQA Biology Paper 2 Revision Booklet (PARTS 1, 2 & 3)

These are three revision booklets to prepare AQA A Level Biology students for Paper 2 exams.

Each booklet has every specification point broken down into smaller sections which contains:
• the specification points so that students can prepare well for answering AO1 questions
• clear and concise revision notes and diagrams on every specification point
• recall questions and answers so students can practice their retrieval of key information
• model answers to common exam questions
• summary questions and answers
• hints and tips to help students remember and understand tricky topics
• practice exam questions and mark schemes
