Revision that fights back.

Quiz battles built on the KS3, GCSE and A-Level specs you're actually sitting. Answer right, splash your rival, climb the River Ranks.

Free for students. No card needed.

Built on the specifications from AQA, OCR, Pearson Edexcel and WJEC Eduqas, plus the KS3 National Curriculum.

How it works

Ten minutes on the bus counts. Here's what a session looks like.

  1. Pick your course

    Choose your key stage, exam board and subject. Every question is tagged to a spec point, so you only revise what's on your paper.

  2. Battle or practise

    Jump into a ranked 1v1 against someone at your level, or race the clock solo in River Rush. Wrong answers come back later until they stick.

  3. See what to fix

    Your progress map shows which topics are solid and which need work, so your next session starts where it matters.

Game modes

Different ways to play, same goal: more marks in the exam.

Ranked Revision

Ranked 1v1 revision battles. Get matched with a student on the same course, trade questions in real time and win Elo for every victory. Each correct answer sends a splash attack across the river.

  • Matched by course and skill
  • Seasonal ranks from Pebble to Master Otter
  • Rematch or review every question afterwards

River Rush

Solo, against the clock. Answer as many as you can before the current carries you off, then beat your best.

Questions

Can't find your answer? Get in touch.

Which exam boards do you cover?

AQA, OCR, Pearson Edexcel and WJEC Eduqas at GCSE and A-Level, and the National Curriculum at KS3. Questions are tagged to individual spec points so you can filter to exactly what's on your course.

Who writes the questions?

Practising UK teachers and examiners write and review every question bank. Students can flag any question they think is wrong and we check it.

Is it safe for my child?

There is no free-text chat. Players pick nicknames from an approved list, and teachers control who joins their classes. We never show ads to students.

Does it work on phones and Chromebooks?

Yes. Ottered runs in any modern browser on phones, tablets, laptops and Chromebooks, with nothing to install.

Can I cancel Otter Plus at any time?

Yes. Cancel from your account settings and you keep Plus until the end of the period you've paid for.

Your next revision session could be a win.

Example reviews while Ottered is in development.

The 1v1 battles are honestly addictive. I revised more for my chemistry mock in one week than I did all term, and went from a 5 to a 7.
MayaGCSE student
Having everything split by exam board is such a relief. I only revise what's actually on my AQA paper now, and the notes are written by real teachers.
DanielA-Level student
I set a Revision code as homework on Friday and 27 out of 30 had done it by Monday morning. That never happens with worksheets.
Mrs PatelScience teacher
My son actually asks to do his revision now, mainly so he can earn enough shells to buy a crown for his otter. I'll take it.
SarahParent
Notes, flashcards and exam questions all in one place saved me hours. Ten minutes of flashcards on the bus is my new routine.
AishaGCSE student
Climbing the River Ranks with my mates turned revision into a competition. I'm still annoyed I finished the month in second place.
