The problem with revision

Most students revise by reading. Exams reward answering.

Plenty of students know more than their marks show. They lose marks on technique: missing what the command word wants, describing when they should explain, stopping before the judgement. GCSE Gym trains both halves, the knowledge and the way you answer, a little every day.

How it works

01

See where your marks are

Your strength map colours every topic from 'needs work' to 'strong', so you always know what to train next.

02

Learn it

New or shaky topic? Short revision notes, must-know flashcards you flip and test yourself on, and a real exam question built step by step so you see how the marks are won.

03

Train it

A quick warm-up, then five exam-style questions in your board's style, marked like an examiner, with the one fix for your next mark and a two-minute rep to lock it in.

04

Keep it

Topics come back after 2, 7 and 21 days, so they're still there in May. Streaks, badges and a weekly summary show how far you've come.

Everything you need, nothing you don't

A tutor that finds the gap

It doesn't just explain. It works out where your understanding breaks, fixes that, and checks it stuck.

Homework help, not homework done

Your sparring partner: it draws out what you know and shows you how to score better, never does it for you. Then it trains what you found tricky until you've mastered it.

Crib sheets to print

One page per topic: the key things to know, a diagram, and how to answer each type of question. Download, print, pin it up.

Test on Tuesday?

Tell us what's on it and when. You get a short plan for every day until then, and a calm top-up on the morning.

Keeps pace with school

Tell it what you're doing in class and sessions follow, or lock in an old topic, or mix it all up.

Photo marking

Snap your maths working and get method marks, not just a right or wrong.

Don't know your exam board?

Start on a general course covering what every board teaches, and switch when you find out.

A help assistant answers questions about the app straight away, and a real person is one tap away.
