What is ExamGPT?

ExamGPT product thumbnail

ExamGPT, by Excelas, is an AI marking platform for UK GCSE exam papers in mathematics and the sciences. Schools scan completed papers, upload them through the portal, and receive marked scripts and analytics back within hours. The system supports major UK exam boards including AQA, Pearson Edexcel, OCR, and WJEC Eduqas.

Why ExamGPT works

Marking mock exams eats teacher evenings and weekends and the feedback often arrives too late to change how students revise. By scanning papers in batch and returning marks plus per question analytics quickly, ExamGPT cuts the marking turnaround so teachers can act on knowledge gaps before the next lesson rather than after the next mock.

ExamGPT features

  • Subject and board coverage. Marking is available across GCSE mathematics and sciences for AQA, Pearson Edexcel, OCR, and WJEC Eduqas so departments can run mocks across the curriculum.
  • Scanned paper ingestion. Teachers scan physical answer booklets and the system reads handwritten responses, so students do not need to type answers into a separate system.
  • Per student analytics. Returned data breaks down performance by topic and question so teachers can see which concepts the class missed rather than only final scores.
  • High volume turnaround. The page mentions 20,000+ daily capacity and a 24 hour service level guarantee so a whole year group can be marked in time for the next lesson.

Who ExamGPT is for

  • Heads of maths and science departments at UK secondary schools running multiple mock exams per term who need faster turnaround to feed back to students.
  • Classroom teachers who currently spend evenings marking GCSE papers and want that time back for lesson planning and interventions.
  • Multi academy trust assessment leads coordinating standardized mocks across schools who need consistent marking and comparable analytics across sites.
  • Tutoring companies preparing students for GCSE retakes that want fast, structured feedback on practice papers between sessions.
