A-Level Biology is a subject packed with fascinating topics regarding life, from the molecular machinery of DNA replication to the intricacies that sustain life, the impact of ecosystems, and more. But with so many theories, structural content, practical work, and already existing pressure of exams, it’s no wonder why many students find it challenging.
Amidst this, one of the more commonly asked questions by the students is “How many papers are there in A-Level Biology?”
Whether you’re enrolled in a school or learning independently, it’s important to understand how the Cambridge International A-Level Biology (9700) exams are structured, because the number and types of papers will directly impact how you study and revise.
This guide breaks down how to prepare smarter, revise better, and walk into the exam room feeling confident on your very important day.
Understanding the A-Level Biology Paper Structure
Before diving into your revision, it's essential to understand how Cambridge A-Level Biology (9700) is assessed. The exam is divided into five different papers—three at the AS-Level and two additional ones for the full A-Level.
If You’re Taking AS Level Biology:
You'll sit for the following 3 papers:
Paper 1: Multiple Choice
Duration : 1 hour 15 minutes
Content : AS syllabus questions in MCQ format
Weight : 31% of AS (15.5% of A-Level)
Paper 2: Structured Questions
Duration : 1 hour 15 minutes
Content : Short and extended response questions from AS topics
Weight : 46% of AS (23% of A-Level)
Paper 3: Advanced Practical Skills
Duration : 2 hours
Content : Lab-based practical exam
Weight : 23% of AS (11.5% of A-Level)
If You’re Taking Full A-Level Biology:
You’ll need to complete all five papers:
Paper 4: Structured Questions (A2 content)
Duration : 2 hours
Content : Examines topics from the second half of the syllabus
Weight : 38.5% of A-Level
Paper 5: Planning, Analysis, and Evaluation
Duration : 1 hour 15 minutes
Content : Data analysis, experiment planning, and evaluation
Weight : 11.5% of A-Level
Another valuable strategy is learning how to use the mark scheme effectively. While it’s useful for checking answers, its real value lies in revealing how marks are awarded and what examiners look for in high-scoring answers. Pay attention to recurring question types and themes that appear year after year, as exams often follow predictable patterns. Recognising these trends can help you prepare strategically and approach questions with a clear idea of what’s required.
