Exam prep for Cambridge, AQA, OCR and Edexcel
You knew it.You still lost the mark.
Apollo marks your past-paper answers point by point against the mark scheme. You see exactly which mark slipped and why, then you win it back.

3A car of mass 1200 kg accelerates uniformly from rest to 24 m s⁻¹ in 8.0 s along a straight, horizontal road. The driving force on the car is 4800 N.
- (a)Calculate the resultant force on the car.[2]
- (b)Determine the magnitude and direction of the total resistive force on the car.[2]
Mark scheme hidden until you submit
Your answer
Scan, upload or type your working.
This is a typed attempt. Change it or submit it as it is.
A sample question with a demo rubric. Inside Apollo you practise real past-paper questions, marked against the official scheme.
How it works
What happens to a lost mark.
Most revision stops at the score. Apollo follows the mark until you have it back.
01Marked
Marked like an examiner would.
Each answer is checked against the scheme for that exact question, one mark point at a time. The scheme stays hidden until you submit.

02Named
Filed as a pattern, not a score.
The miss goes on your review list with the marks it cost. Lose marks the same way again and Apollo notices the repeat.

Progress that means something.
Mastery only moves on marked work. Topics you have not been tested on stay unassessed instead of being guessed.

Apollo Teacher
A tutor that has already read your answer.
Teacher opens with the question, your working and your mistake history in front of it, so you never start by explaining what you did.
Asks before it tells
One question at a time, hints when you are stuck, and the full explanation when you need it.
Shows what it checked
Every lookup appears in the reply, so you can see what it used.
Answers straight questions straight
Ask what a command word means and you get the answer, not a quiz.
Maths keyboard built in
Symbols, Greek letters and equation templates, with a preview before you send.
Scripted demo. Once you sign in, Teacher works from your own questions and attempts.
Visual answers
Graphs you can drag. Reactions you can balance.
When a picture beats a paragraph, Teacher builds one into the reply. These are the real thing. Have a go.
The same explorers appear inside Teacher replies and questions.

Sit the whole paper.
Pick a past paper, start the clock and sit it properly. When you hand in, every question is marked, including the ones you left blank.
01Your timer and working save as you go.
02Type your answers, photograph your pages or upload a PDF.
03The mark scheme unlocks after you submit.
04Marks for every question. Never a guessed grade.

Ground rules
The rules Apollo plays by.
01
No peeking
Mark schemes stay hidden until you have submitted an answer.
02
No guessed grades
You get marks and the reasons for them. Apollo never predicts a grade.
03
No evidence, no mastery
A topic only counts as secure once marked work shows it.
04
Nothing hidden
Teacher shows what it looked up. You can dismiss anything it remembers about you.
05
Your work stays private
Uploads are private to your account, and AI requests run with zero data retention.
FAQ
Questions students ask.
Yes. Student accounts are free. You sign in with Google or an email link, so there is no password to forget.
