Exam prep for IB · A-level · IGCSE

Learn the structure.
Improve your grades.

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.

The same answer, marked two ways

"Correct" isn't the same as full marks.

Here's one exam-style question, reviewed by a general AI and then by Modulus with marking patterns in mind. Watch where the mark quietly disappears.

Physics HL · Paper 2 · question 3a

A car accelerates from rest to 24 m s⁻¹ in 6.0 s. Calculate its acceleration. [2]

a = (v − u) / t a = (24 − 0) / 6.0 = 4
Generic AIlooks right
"Correct — the acceleration is 4. Nicely done!"
Modulus · marking-aware review 1/2
M1 Correct method — divides change in velocity by time. Awarded.
A1 Answer weak: no unit. In many marking rubrics, the expected answer is 4 m s⁻². This is the kind of detail worth making automatic.

You know the content.
You still lose marks.

That's the gap Modulus closes.


How Modulus works

Practice, feedback, then aimed back at your weak marks.

A loop, not a content dump. Each round is generated fresh, reviewed for marking patterns, and used to decide what you practise next.

01

Generate exam-style questions

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.

02

Get marking-aware feedback

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.

03

Revise where you actually lose marks

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.

Stop guessing what loses you marks

For IB, A-level, and IGCSE students who know the content but keep dropping the same kinds of marks.

  • Fresh practice designed around your paper format
  • Mark-by-mark feedback, not "correct / incorrect"
  • Revision aimed at your recurring mistakes
// teachers

See where the class tends to lose marks

Set practice in seconds and see the mark patterns across a class — the command terms, the units, the structure they miss.

  • Generated practice without writing every question
  • Marking-aware feedback you can review and teach from
  • Patterns you can teach to, not just grades
