What the data across 31,400 scripts says
We publish our aggregate numbers because most tutoring claims are unfalsifiable. These are averages, not guarantees, a student who does nothing with the report moves nothing.

Figures cover papers marked between September 2023 and June 2026 for students who submitted three or more scripts. Grade movement is measured against the student's first marked paper.

In their words
Students, parents and departments
"The annotated script was the thing that changed it. My son could see the exact line where the method mark stopped. He went from a 5 to a 7 in Maths across two terms."

"I had no idea my English answers were sitting in band 3 because I was describing rather than analysing. Seeing my own paragraph rewritten at band 4 made it obvious."

"We use GCSE Feedback for departmental mocks. Thirty scripts marked and moderated in under a week freed my team for actual teaching, and the topic breakdowns fed straight into our intervention list."
Sarah Whitfield
Head of Science, secondary academy · Leeds
"As a private tutor I cannot mark full papers for every student. Sending them here gives my students examiner-standard marking and gives me a report to plan the next session from."
Tom Ashby
Independent tutor · Bristol
"Turnaround was genuinely 48 hours, twice. The feedback report was specific rather than generic praise, which is exactly what we were paying for."
Helen M.
Parent, Year 10 · Glasgow
"The topic tests found the gap fast. Two tests in, we knew it was quantitative chemistry and nothing else, and we stopped wasting revision time everywhere else."
