Your board's A-level Biology specification as lessons and questions, built from Mr Exham's videos, with personalised practice until your exams.
Mr Exham's videos stop and ask you questions as you watch. This course is built the same way: a lesson, then questions, then practice on what you got wrong.
In the order your board's specification lists them, under its own codes, with Mr Exham's video wherever he has made one. Each lesson explains the idea before it asks you anything about it.

Put the stages of transcription in order. Match each heat exchange mechanism to its process. Count the hydrogen bonds in a DNA section with 6 A–T and 4 C–G base pairs. You find out what you know by answering.

What you get wrong gets practised again within days, what you know comes back later. So you will remember biological molecules from your first year at the final papers, and the spring isn't spent relearning everything.

Type a question about any topic and the answer is drawn from this course's own lessons, with a link back to where it is explained. No weak sources, no AI hallucination.

From the first topic on your board's specification to the last, every topic has its lessons and its questions.










The course follows your board's specification in order, so you always know which part you are on and what is left.
Each lesson ends in questions, so you find out what you actually know before the exam does.
Your final papers can ask about the whole course, so first-year topics keep coming up in practice and still feel fresh at the exam.

Built for AQA A-level Biology (7402)
From the AQA 7402 specification and Mr Exham's lessons
Put in the date of your first paper and the app spreads the whole course across the weeks you have, with review built in.
Ordering, matching, tables, labelling a diagram, fill the blank, flashcards. The same idea gets asked more than one way, so you learn the biology, not the look of the answer.












I'm a biology teacher, and I started MrExham.com in 2013 for students studying IGCSE, A level and IB. My videos have since been watched in more than 130 countries.
Every video takes one topic of the specification, with its diagrams and practicals, and stops to ask you questions as you go.
Watching a video feels like revision, but you learn far more by answering questions. So this course asks you about every topic, until you know it.

Yes, and they stay free on YouTube. The course is where you learn your specification in order and get asked about it, with the things you get wrong coming back before the exam.
Yes. Each course is built for one board, under its own codes and in its own order. Pick yours above and you get that one.
Usually the wording. Mark schemes credit particular terms, and the course asks for the exact term in its gap-fill and matching questions, so the right words become the ones you use.
No, your teacher assesses that in the lab. The course asks about the required practicals as written questions, the way your papers do.
No. Every question in the app has a checkable answer, so it can't mark a long answer and doesn't pretend to. What it drills is the biology those answers are built from: the facts, the processes and the reasons behind them.
No. You choose which topics go into your plan, so you can start with what your class has covered and add the rest as you go.
