Built for Edexcel International, not adapted to it.
Edexcel International A Level Biology spans 8 topics, from Molecules, Transport and Health to Coordination, Response and Gene Technology, and Exaim covers all 78 subtopics — with practice written for the Edexcel International specification rather than adapted from another board's.
Biology is a subject of precise definitions: an answer that is nearly right in everyday words often earns nothing, because the mark scheme is waiting for one specific term. Exaim marks your written answers the way Edexcel International's own examiners do, one marking point at a time, so every question shows you where a real mark was won or lost.
What you get with every Edexcel International Biology course.
The same thing in every subject: real exam questions, marked properly, and a clear next step.
Marked like an examiner would
Write the answer in full and get it checked against your board’s published scheme, point by point, with the wording that would have earned each mark.
Built for your exact board
Not a generic summary written for everyone. Questions, notes and mark schemes all follow the specification you are actually sitting.
Practice, papers and timed mocks
Topic questions when you are learning something, full papers under exam conditions when you are ready to find out.
Handwritten work included
Photograph a written answer or a diagram and it is marked the same way — so you can revise on paper if that is how you work.
A plan that reorders itself
Every mark you drop becomes scheduled practice, so the weakest topic is always next and you never open the app wondering what to do.
How Edexcel International Biology practice actually works.
Not a video you watch. A question you answer, marked the way an examiner would.
01
Answer a real exam question
Type it, write it on paper and photograph it, or draw the diagram. Full sentences, the way you would in the exam.
02
It is marked point by point
Checked against your board’s published mark scheme, one mark point at a time — with the wording that would have earned the ones you missed.
03
Your plan moves
Every mark you drop becomes scheduled practice. The weakest topic is next, so you never open it wondering what to do.
Studying a different board?
Biology is covered for every board we support at A-Level. The specifications differ, so the practice does too.
Common questions.
How is Edexcel International A Level Biology marked on Exaim?
You write a real exam-style answer and it is marked against Edexcel International's published mark scheme, point by point — the same marking points an examiner uses. You see exactly which points you earned, which you missed, and the wording that would have earned them.
How many topics does Edexcel International A Level Biology cover?
The whole specification: 8 topics, from Molecules, Transport and Health to Coordination, Response and Gene Technology, broken into 78 subtopics you revise and get tested on. Every one has practice, and the full list is on this page.
Is this built for Edexcel International, or a generic biology course?
Built for Edexcel International. The questions, the topics and the marking all follow the Edexcel International specification — not one generic biology course with a different board's name on the front.
Can I try Edexcel International A Level Biology for free?
Yes — start free with no card. You can practise Biology questions and see exactly how the marking works before you decide anything.
I sit a different board — is Biology covered for others?
Yes. A-Level Biology is covered for AQA, Edexcel Biology A and Edexcel Biology B too, each built for that board's own specification. The links are further up this page.
