How it works

Three steps to
dead centre

Past papers are the best revision there is. Bullseye takes the friction out, so every minute you put in goes on questions that score.

  1. Pick your course

    Choose your exam board and qualification, AQA, OCR or Edexcel, GCSE to A-Level. Add the subjects you're actually sitting.

  2. Drill it by topic

    Every past-paper question is cut out cleanly and grouped by topic. Hit your weakest topic first, not page 37 of a PDF.

  3. Mark it like an examiner

    Flip to the real mark scheme for that exact question in one tap. Learn precisely what earns the marks, and what doesn't.

The old way

Downloading past papers

  • Scrolling 40-page PDFs to find one topic
  • Hunting through a separate mark scheme file
  • Re-doing questions you already know
  • Notes, flashcards and papers in five different places
The Bullseye way

Revision that hits the target

  • Every question cut out and sorted by topic
  • The matching mark scheme one tap away
  • Straight to the topics that cost you marks
  • Papers, flashcards, notes and mind maps in one place

FAQ

Questions?
Answered.

Which exam boards and levels do you cover?

AQA, OCR and Edexcel, from GCSE through AS to A-Level. Every course is built from that board's real past papers and mark schemes.

How is this different from just downloading past papers?

Past papers come as long PDFs, with the mark scheme in a separate file. Bullseye cuts every question out individually, groups them by topic and puts the matching mark scheme one tap away, so your time goes on answering questions, not scrolling.

What's free, and what does Pro add?

Free gets you every past-paper question filed by course, full question papers, flashcards, notes and mind maps, no card needed. Pro (£5 a month, or £45 a year) unlocks the matching mark scheme for every question, self-marking with score tracking, and progress reports you can share with a parent.

Can I cancel any time?

Yes. Cancel in two clicks from your account and you keep Pro until the end of the period you've paid for. If Pro isn't for you, ask for a refund within 14 days of your first payment.

I'm a parent. Can I pay for my child?

Yes. Your child taps “Ask a parent to pay” and sends you a private link. You pay securely through Stripe and their account is upgraded instantly, no need to share passwords.

Does it work on my phone?

Yes. Bullseye runs in your browser on any phone, tablet or laptop, nothing to install. Your flashcards, notes and mind maps save to your account, so they're there on every device.

Can I make it look the way I like?

Completely. Switch between dark and light, pick your accent colour, heading font and layout density from the Customise panel, try it from the top of this page.
