I spent years watching students revise hard and remember almost nothing. So I built this.

I used this method myself for GCSEs and A levels: treat the spec as a complete list of everything that can be asked, retrieve each point from memory until it sticks, and practise turning that knowledge into the language examiners actually want. At the time it meant printing the specification, taking over the dining table at home with notes and piles of handmade flashcards, and refusing to call something revised until I could reproduce it without looking. It was, in retrospect, just spaced repetition with a lot more paper.

Teaching and tutoring showed me what happens when students do not do this. I have taught in state schools, a private school, and internationally (in Budapest and Saudi Arabia), and the pattern is identical everywhere. They read. Convincingly, diligently, sometimes with six different coloured pens, occasionally producing a diagram so beautiful it belongs in a museum. They rewrite the textbook in neater handwriting and call it revision. It feels productive right up until an exam question appears and the answer does not.

The alternative is less Instagrammable. Active recall means short, specific tasks and honest feedback about whether something actually went in. Not motivation, not a love of Biology, not being the kind of person who voluntarily makes revision notes on a Saturday morning. And because I am a qualified teacher, I know the specification inside out, how mark schemes are written, and the gap between understanding a topic and being able to answer questions on it under timed conditions. That knowledge shapes every note and every question here. The site works out what to revise and when; students just have to show up.

Between classroom teaching and around a thousand hours of one-to-one tutoring, I've met every version of the student who finds revision hard for reasons that have nothing to do with Biology: ADHD, autism, anxiety, perfectionism, or simply never having been shown what active revision actually looks like. Plenty more are ordinary teenagers who are tired, slightly behind, and do not understand why nothing seems to be going in. They shaped the design as much as the high-achievers did.

That shaped real choices, not just good intentions. There are no streaks or flashing rewards to break, and the account settings let each student set a dyslexia-friendly font, larger text, wider spacing, a calmer background tint, or reduced motion — plus a Calm mode that hides exam countdowns and time pressure. You decide what your version looks like.

None of it is theoretical. The spec and mark schemes shape every note and every question here. Parents aren't gambling on accuracy, and students aren't gambling on another wasted evening of highlighters and good intentions.
