Why students use it

A diagnosis, not just a score

Real exam conditions

Every diagnostic is timed. The clock starts when you do and the paper submits itself when time is up, just like the real thing.

Instant scoring

Your paper is marked the moment you submit, with a question-by-question breakdown and worked explanations.

Know where you stand

A skill-by-skill report with the time you spent on every question shows exactly what cost you marks and what to work on next.

The studio behind the papers

A real tutoring studio, not a question bank

Every diagnostic here is written, marked and followed up by The Complete Equation, a 1:1 online mathematics tutoring studio. Watch the short intro, then put a paper to the test.

How it works

From diagnostic to a plan in three steps

01

Take a free diagnostic

Pick your course (IGCSE, A-Level, AP or SAT) and sit a short timed paper written by our tutors.

02

See your skill report

Instant marking shows your score and a breakdown by skill, so the gaps are obvious.

03

Fix the gaps 1:1

Book a free demo class and the tutor who wrote your paper builds a plan around your report.

After your diagnostic

Turn your skill report into a plan
