Why ExamFix marking is different
ExamFix is built specifically for GCSE Science. Your answer is checked against question-specific marking criteria so you can see what earned credit, what was missing and how to recover the marks.
The AI supports the marking workflow; it is not treated as an official examiner, exam-board mark scheme or final authority on your grade.
How ExamFix uses AIEach question uses its own marking points or level-of-response rubric rather than a generic chat judgement.
Practice is matched to AQA, OCR Gateway or Pearson Edexcel, plus your course and tier where applicable.
See which scientific ideas earned credit, which points were missed and what to improve next.
ExamFix is a revision tool. Baseline grades are indicative working-at levels, not official predicted grades.
