Most revision tells you what to learn.
This tells you what you’re getting wrong.
Sit a past paper
Properly. On paper, timed, no notes. Pick one from the tracker and click through — every paper links straight to the real thing, mark scheme included.
Mark it yourself
Against the official mark scheme, exactly as an examiner would.
Enter your marks, part by part
Not “I got 58”. Question 1a: 2 out of 3. Question 1b: 0 out of 4. It takes a few minutes.
Find out what's actually costing you
You get your real grade, and a list of the specific topics losing you marks — with practice built for each one.
Why part by part?
Because “58 out of 100” tells you nothing you can act on.
Dropping one mark on a six-mark question and dropping all six look identical in a total. They’re completely different problems. The first is a slip. The second means you can’t do that topic yet.
Entering marks part by part is the only way to tell them apart — so we can send you to practise the thing you actually can’t do, instead of the thing you rushed.
It takes about three minutes. It’s the three minutes that make the other two hours useful.
Your grade, properly worked out
Real boundaries
Every paper is marked against the grade boundaries Pearson actually published for that paper and that series. Not a rough percentage. If June 2019 was a brutal paper, your grade reflects that it was a brutal paper.
Your last three papers, not your last one
One paper is noise — a bad morning, a topic that happened to come up. Your headline grade comes from your last three, which is a far better guess at what you’d get tomorrow.
Honest about what's a guess
Papers that aren’t official Edexcel ones are marked as estimates and kept out of your headline grade entirely.
We won't spoil your mocks
Here’s something no other site does.
If we sent you to practise question 7 from a paper you haven’t sat yet, that paper is ruined — you can’t use it as a real mock any more. You’ve burned it for one question.
So we never do. Every piece of practice we send you to is either from a paper you’ve already sat, or from our own question packs. Your unsat papers stay clean.
The practice packs
When a topic is costing you marks, you get a pack built for that topic. More than 350 packs across GCSE Higher, AS, A level and A level Further Maths.
Every question is original to this site — written in the exam board’s own style, with a full mark scheme laid out mark by mark, so you can mark your own work exactly as an examiner would.
What it costs
The tracker is free. Always. Enter your papers, get your real grade, see exactly which topics are costing you marks. That doesn’t cost anything.
Your first three packs are free too — the first three topics we diagnose you as needing, in full, with the mark schemes.
After that, £19.99 for a year, or £9.99 for three months. Nothing renews automatically.
And if your school is on our list, it’s all free — sign up with your school email address and there’s nothing to pay. Pricing
What this isn't
We don’t mark your paper for you. You mark it yourself against the mark scheme — partly because marking your own work against an examiner’s standard is where a lot of the learning happens, and partly because nobody can reliably mark handwritten maths from a photo yet.
We don’t cover every subject. Right now it’s Edexcel maths: GCSE Higher, AS, A level and A level Further Maths. What's covered
