Launching 2026
IB, marked to the mark scheme.
IB Biology, Chemistry, Physics and Maths are coming to Exaim in 2026 — every answer marked against the published mark scheme, point by point. Here is what we’re building, and you can start free on GCSE and IGCSE today.

What IB will do, from day one.
The same thing our GCSE and IGCSE courses do today — you can try all of it free right now, on the subjects that are already live.
Marked to the mark scheme
Every written answer checked against the published scheme, point by point — with the wording that would have earned the marks you missed.
Built for your exam board
Practice written for the specification you actually sit, not one generic course with your board’s name on the front.
Always know what to revise
A study plan that reorders itself around the topics you keep dropping marks on, so the next session is always the one that moves your grade.
IB lands in 2026.
Start free on GCSE and IGCSE today, and you’ll be first to know the day IB goes live.
