You write the answer. We show you what it was worth.
Every mark on your exam paper is defined in a document your board publishes. Exaim marks against that document, point by point — and tells you the words that would have earned the ones you missed.

One question, start to finish.
The whole loop is three steps. This is all of it, with nothing hidden behind a click.
01
You answer a real exam question
Filtered to your subject, board and topic. Write it in full sentences the way you would in the exam — or write it on paper, photograph it, and submit that instead.
Explain why the rate of reaction falls when the enzyme is heated above 50 °C.
Your answer
The enzyme denatures and the active site changes shape, so it stops working
02
It is marked against the published scheme
Your board publishes exactly how each mark is earned. Your answer is checked against that document one mark point at a time, so you get a score with a reason attached to every mark awarded and every mark refused.
The enzyme denatures and the active site changes shape, so it stops working properly.
- Enzyme denatures+1
- Active site changes shape+1
- Substrate no longer binds−2
03
You find out what to write next time
The wording that would have earned the marks you missed, and the habit behind them — most dropped marks are a pattern, not an accident, and the pattern is the thing worth fixing.
A better answer
“…so the active site changes shape and the substrate can no longer bind.”
Name the effect on the substrate and both missing marks are yours.
Your examiner’s note
You’re not missing the topic. You’re losing marks because your explanations stop one step too early.
What actually happens to your answer.
Your exam board publishes exactly how every mark is earned. Exaim is built on that document — and only one step in the chain is done by a model.
- Written answers, not just multiple choice
- Typed today; handwriting and diagrams in development
- The exact wording that would have earned the mark

Gaps become practice
A mark scheme is a list of things you either said or did not say.
Grading it as a list is the only way to tell you which one you missed.
What the model does, and what it does not.
“An AI marks your essay” is the sentence people stop at, so here is the whole of it.
What it does
- Compares your answer to each mark point in turn
- Explains why every mark was awarded or refused
- Shows the wording that would have earned the ones you missed
- Reads handwriting, diagrams and typed answers alike
What it does not
- Invent the mark scheme — that is your board’s published document
- Write your coursework, or anything you hand in
- Replace your teacher’s judgement on a borderline answer
- Predict your final grade, which needs a study we have not run
What you get with every Exaim 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.
