How to revise A-level biology

Effective revision requires you to retrieve and apply knowledge, not only reread it. Write answers without looking at the notes, mark them against your board’s current mark scheme, revisit weaker topics over several sessions and practise interpreting diagrams and data.

Write the answer before you look at one

Reading a model answer is mostly recognition: the words are all familiar, so nothing tells you that you could not have produced them. Every question in the question bank keeps its mark scheme shut until you ask for it.

Mark your answers against the scheme

Many short questions award marks for specific points. Extended responses may use a different marking structure, so follow the scheme supplied with the question. Record the points you missed and practise them again later. The command words page sets out what each kind of question asks for.

Learn the terms, and what makes each one precise

Many marks turn on exact terms in biology. “Water moves from high to low concentration” and “water moves down a water potential gradient” are not two ways of saying the same thing; the first is wrong because concentration is the wrong quantity. Learn what each term means and why the loose version fails, rather than memorising a script: an examiner credits accurate meaning expressed in the necessary terminology, and your own board’s mark schemes are the authority on accepted wording. The definitions page carries every term the lessons define, and the flashcards drill them.

Space it out, and let something else pick the order

Revising a topic three times in one evening feels far better than revising it on three separate days, and does less. The flashcard player brings a card back sooner when it went badly and later when it went well, so it spaces your reviews for you; it also means you do not spend the session on the topics you already like.

Use the diagrams as things to redraw

Every figure in this library was drawn to carry one idea. The useful thing to do with one is to shut the page, draw it, then compare. A diagram you can reproduce from memory is a diagram you can explain in a written answer, which is what the question will ask for.

How practical skills are assessed

Practical skills are assessed differently by each awarding organisation. AQA, OCR A and Pearson assess practical knowledge in written papers and report a separate practical endorsement. Cambridge International 9700 includes a timetabled practical examination and a separate planning, analysis and evaluation paper. Check the assessment structure for your qualification.

The fourteen capabilities set out what you have to be able to do at the bench and in the field, with the calculations each one involves and the errors that are common in it.

Use the checklist to choose weaker topics

The revision checklist holds every objective in the curriculum. Rate what you could write down now, not what you would recognise, then use the filter to show only what needs work.

Coverage maps are available for AQA 7401/7402, OCR Biology A H020/H420, Cambridge International 9700, Pearson Edexcel Biology A (Salters-Nuffield) 8BN0/9BN0 and Pearson Edexcel Biology B 8BI0/9BI0. Use the relevant route map to check what InkBiology covers, and use your awarding organisation’s current specification as the final authority on examinable content.
