ChatGPT answers the question. Modulus trains you to answer it in the way marks are commonly awarded — with feedback on method, accuracy, units and structure.
Free trial for partner schools · built by IB & A-level students
A real Modulus review of one exam-style question. The formula is right and the substitution is right — the mark still goes missing on the last line. That's the detail a general AI never mentions.
You know the content.
You still lose marks.
That's the gap Modulus closes.
A loop, not a content dump. Each round is generated fresh, reviewed for marking patterns, and used to decide what you practise next.
Not a fixed bank you exhaust. Modulus generates fresh practice designed around the format of your subject and level — Paper 1 / 2 / 3, SL vs HL, calculator rules, command terms, mark distribution — so you always have something new to sit.
Every answer is reviewed against marking patterns: method marks, accuracy marks, and the details examiners often credit or withhold. You see which points look secure, which look weak, and why.
Modulus tracks the patterns — the units you forget, the command terms you misread, the working you skip — and sends the next round straight at them. Your time goes to the marks you keep dropping, not the ones you already have.
Answers the question. Tells you it's right.
Trains you to answer it with the marking details in mind.
For IB, A-level, and IGCSE students who know the content but keep dropping the same kinds of marks.
Set practice in seconds and see the mark patterns across a class — the command terms, the units, the structure they miss.
We build from inside schools, not by selling to them from the outside — aligned to your timetable and your programmes.
