For students
Practice should not end with a score. Students need to understand what earned credit, what was missing and what a stronger answer looks like while the question is still fresh.
Why we built ExamFix
Knowing the science should translate into marks.
ExamFix began with a pattern seen year after year in GCSE Science classrooms: students could understand the content, explain an idea in conversation and still leave marks on the exam paper.
Built by a GCSE Science teacher. Shaped by the problems students face in real exam practice.
The problem
Students were revising. But too many still did not know why marks were being lost.
The issue was not always a lack of knowledge. Often, it was the gap between knowing the science and expressing it in a way that answers the question precisely enough to earn credit.
A student might understand respiration, electrolysis or forces, yet lose marks because an explanation is incomplete, a comparison is vague, a calculation is not shown clearly or a longer response misses the chain of reasoning the question requires.
Traditional revision is excellent at helping students learn content. What was missing was a fast, repeatable way to practise the next step: answer an exam-style question, understand the feedback, improve the response and try again.
The idea
Build the feedback loop students need after the answer is marked.
ExamFix was built around a simple belief: useful practice should make the next answer better. The mark matters, but the learning happens when a student can see what was credited, identify the gap and improve the same response.
01
Answer
Attempt an exam-style question independently and commit to a response.
02
Understand
See which ideas earned credit and which scientific points or reasoning are still missing.
03
Improve
Rewrite the answer while the feedback is fresh and turn understanding into a stronger exam response.
Who we are building for
One problem. Three perspectives.
ExamFix has to work for the student answering the question, the teacher supporting the learning and the school responsible for making technology useful, safe and purposeful.
For teachers
Teachers need students doing more purposeful exam practice without every attempt creating another pile of marking. ExamFix is designed to reinforce the feedback loop teachers already use in the classroom.
For schools
Schools need technology that supports teaching rather than replacing it: consistent exam practice, useful insight and AI that is focused on a clear educational purpose.
Our vision
Make high-quality exam feedback available whenever a student practises.
Our vision is for every GCSE Science student to be able to understand why an answer lost marks, what a stronger answer needs and how to improve it — without having to wait for the next lesson or guess from a mark scheme alone.
Technology should not replace great teaching. It should give students more opportunities to practise well, make feedback more immediate and help teachers spend more time on the parts of learning that need a human.
What guides us
The product should earn trust in the classroom.
Start with the science and the specification, not the AI.
Show students why marks were earned or lost, not just a final score.
Use feedback to drive another attempt, because improvement happens in the rewrite.
Keep teachers at the centre of learning and use technology to extend their impact.
Fix the answer. Learn from the feedback. Get better at the exam.
That is the idea ExamFix started with, and it is still the standard we are building towards.
