Exam-board routes
These are the eleven A-level biology routes this library is written for. Whichever of them you are sitting, you get the same thing today, and the same thing is true of all eleven.
InkBiology teaches A-level biology from a curriculum of its own, written to hold more than any single specification asks for. No board has been mapped against it. That means no lesson, question or card on this site is claimed to cover any part of any of these routes, however closely it reads like it does. The overlap is large, because A-level biology is A-level biology, so the lessons are worth your time on any of these specifications. What is on your paper is what your board says is on it, and each card below links to the document that says so.
AQA Biology
What you get today: the whole library, free, and no claim that it covers this route. The lessons are written from our own curriculum of A-level biology rather than from this specification, and nothing here has been checked against it statement by statement. They are useful to you; they are not a substitute for what your board publishes.
How it is examined: Linear; Paper 1 (topics 1-4, 2h, 91), Paper 2 (topics 5-8, 2h, 91), Paper 3 (all topics, 2h, 78, incl. practical/data and one 25-mark essay). Separate Practical Endorsement.
Taught in England. Overseas centres are being withdrawn through 2028/29.
OCR Biology A
What you get today: the whole library, free, and no claim that it covers this route. The lessons are written from our own curriculum of A-level biology rather than from this specification, and nothing here has been checked against it statement by statement. They are useful to you; they are not a substitute for what your board publishes.
How it is examined: Linear; Biological Processes (M1,2,3,5, 2h15, 100), Biological Diversity (M1,2,4,6, 2h15, 100), Unified Biology (M1-6, 1h30, 70). Separate endorsement.
Cambridge International Biology
What you get today: the whole library, free, and no claim that it covers this route. The lessons are written from our own curriculum of A-level biology rather than from this specification, and nothing here has been checked against it statement by statement. They are useful to you; they are not a substitute for what your board publishes.
How it is examined: Staged or linear; P1 MCQ (1h15, 40), P2 AS structured (1h15, 60), P3 Advanced Practical (2h, 40), P4 A-level structured (2h, 100), P5 Planning/Analysis/Evaluation (1h15, 30).
Cambridge says the 2028 update changes nothing significant about what is taught, so both exam windows are recorded together.
Pearson Edexcel Biology A (Salters-Nuffield)
What you get today: the whole library, free, and no claim that it covers this route. The lessons are written from our own curriculum of A-level biology rather than from this specification, and nothing here has been checked against it statement by statement. They are useful to you; they are not a substitute for what your board publishes.
How it is examined: Linear; contextual SNAB topics; Paper 3 carries a pre-release scientific article. Separate endorsement.
Paper 3 carries a pre-release scientific article that changes every year, so no revision library can cover it in advance.
Pearson Edexcel Biology B
What you get today: the whole library, free, and no claim that it covers this route. The lessons are written from our own curriculum of A-level biology rather than from this specification, and nothing here has been checked against it statement by statement. They are useful to you; they are not a substitute for what your board publishes.
How it is examined: Linear; conventional topic order; P1 (T1-7, 1h45, 90), P2 (T1-4+8-10, 1h45, 90), P3 (all, 2h30, 120). Separate endorsement.
