Spots the mistake, not just the wrong answer.

Gave the 15% instead of the new total? Rounded to the wrong place? Markr recognises the slips GCSE students make most and gives a hint, without giving the answer away.

Tutors see which mistakes each tutee keeps making, so the next lesson starts in the right place.

Questions

Which exams does Markr cover?
AQA GCSE Maths (8300) and AQA Level 2 Further Maths (8365).
Is it really free for students?
Yes. Practice, papers and progress are free, with no card needed.
How does marking work?
Markr checks your final answer the moment you submit it, in any sensible form: 1/2, 0.5 and 2/4 are all read correctly unless the question asks for simplest form. Common wrong answers are recognised, so you get a hint about what went wrong. Questions that need working are left for your tutor.
I tutor maths. How do my students join?
Send them your join link. They sign up through it, or join with an account they already have, and their work and progress show up on your Students page.
What happens to my data?
Markr keeps only what it needs to mark work and show progress, and never sells it. Read the privacy notice for the details.
