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 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 don't do this. In state schools, a private school, and internationally, the pattern is identical: they read, diligently, sometimes with six different coloured pens, and rewrite the textbook in neater handwriting and call it revision. It feels productive right up until an exam question appears and the answer doesn't. The alternative is less Instagrammable — short, specific tasks and honest feedback about whether something actually went in. Because I'm a qualified teacher, I know the specification, how mark schemes are written, and the gap between understanding a topic and answering questions on it under timed conditions.

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 looks like. They shaped real choices, not just good intentions — no streaks or flashing rewards to break, and account settings for a dyslexia-friendly font, larger text, wider spacing, a calmer tint, reduced motion, and a Calm mode that hides exam countdowns.

None of it is theoretical. Everything here traces back to the specification and the mark schemes, checked by someone who has marked the real thing. Parents aren't gambling on accuracy, and students aren't gambling on another wasted evening of highlighters and good intentions.
