The reality
Working hard isn't the problem.
Most students revise for hours and still walk out unsure. It's usually not effort that's missing, it's the method. Three things quietly hold every student back.
01
You run out of questions.
Past papers run dry weeks before the exam, so you end up re-doing questions you already know. Feels productive. Teaches you nothing.
An endless supply of original questions, on exactly the topic you need, the moment you need it.
02
You don't know what you don't know.
Left to instinct, students practise the topics they like and avoid the ones that scare them. That's the exact opposite of what lifts a grade.
Your readiness score tracks mastery on every topic and surfaces the weak ones before they cost you.
03
Feedback comes too late.
Textbooks don't mark your work. Past papers sit unmarked for days. By the time it comes back, the moment to learn from it has passed.
Your working gets marked in seconds, with precise feedback on what went wrong and the full method if you want it.
Built on science
Not guesswork. Cognitive science.
The same research behind Anki, Khan Academy, and university adaptive-learning systems. It's working underneath every question you answer.
Bayesian Knowledge Tracing
Every answer updates a hidden model of whether you actually know a topic, accounting for lucky guesses and careless slips. Far more honest than a raw percentage.
Used by CMU & Khan AcademySpaced Repetition (SM-2)
Ebbinghaus proved that revisiting material at the right intervals slows forgetting dramatically. We track when each topic is about to fade and bring it back right on time.
Used by Anki & DuolingoItem Response Theory
Each question carries a hidden difficulty, calibrated against how everyone performs. You're never served something trivial or impossible, just right at the edge of your ability.

Updates in real time after every question you answer
Your Exam Readiness Score. One number that tells the truth.
A single 0–100 score per subject, weighing topic coverage, recent accuracy, mastery depth, and how well knowledge is holding over time. For GCSE it maps straight to a predicted 1–9, and it moves the instant you submit an answer.
You'll know whether you're actually ready instead of guessing, and you won't get false confidence from re-doing questions you've already nailed. Just a clear signal, plus a map of what to fix.

Everything in one place. Nothing you don't need.
Questions that never repeat
Every question is written fresh. Nothing is lifted from a past paper, so you can practise the same topic a hundred times and get a hundred different questions.
Marked in under a second
Submit your working and get a verdict instantly. It's not a blunt answer-check either, it understands method and mathematical equivalence.
Your personal review schedule
Each day you're told exactly which topics to revisit, timed to your own forgetting curve. Revision becomes a quiet daily habit, not a last-minute panic.
Live predicted grade (GCSE)
Your predicted grade moves after every question, 1 to 9, Foundation or Higher, so you always know how far you are from your target.
Know exactly where you stand
Topic-level accuracy, mastery tracking, and your Exam Readiness Score, all live. Clarity instead of guesswork.
Handwritten working accepted
Draw or photograph your working and it gets read, marked, and returned with feedback, just like a real examiner would.
No credit card · Ready in 30 seconds
