Every point explained first
Each course runs through its own specification, topic by topic, under its own codes. Each lesson explains the idea before it asks you anything about it.

of biology
Biology as lessons and questions on your phone, for your own exam board or course, with a study plan to your exam date.

Choose your exam board and we'll take you there.
Learn it, answer it, practise it
Mr Exham's videos stop and ask you questions as you watch. Every course is built the same way: a lesson, then questions, then the ones you got wrong come back.
02Practice
Then the app asks you
Put the path of blood through the heart in order. Match each part of the blood to its job. Pick the vessel that carries blood away from the heart at high pressure. You find out what you know by answering.
- Twelve question formats
- You see where you stand
03Repetition
Older topics come back
What you get wrong gets practised again within days, what you know comes back later. So the first topics of the course are still kept fresh until exam day.
- Spaced practice
- Nothing quietly fades
04Help
Ask when you're stuck
Type a question about any topic and the answer is drawn from the course's own lessons, with a link back to where it is explained. No weak sources, no AI hallucination.
- Ask anything
- Answers from the course
Your course on your phone, topic by topic

“Making Sense of Biology”
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 these courses ask you about every topic, until you know it.

Questions
Aren't Mr Exham's videos free?
Yes, and they stay free on YouTube. The courses are where you learn your specification in order and get asked about it, with the things you get wrong coming back before the exam.
Will it follow my exam board?
Yes. Each course is built for one board or syllabus, under its own codes and in its own order. Pick your level above, then your board, and you get that one.
Does it mark my written answers?
No. Every question in the app has a checkable answer, so it can't mark a long answer and doesn't pretend to. It drills the biology those answers are built from.
What about IB and NCERT?
IB Biology and NCERT Class 11 and 12 are on the way. Sign up on their pages and you'll hear the day they open.
For parents: what is this?
A biology study course in the Voovo app, built with Mr Exham, a biology teacher who runs MrExham.com. It doesn't replace school or a tutor; it's the practice in between. The courses aren't open yet: sign up on this page and you'll hear the day they open, with 10% off.
