Exam Builder
Build an exam around what you need to practise.
This is not built yet. It is the next thing being built, and there is nothing to try on this page today. What already works is below.
What it will do
Choose a subject and course, then narrow it down to the topics you are weakest on. Pick the kinds of question you want — multiple choice, short answer, calculations, longer written answers — how hard they should be, how much maths you want in them, and how long the paper should take. Ailemy assembles a paper from that and marks it the same way it marks a past paper.
It is different from browsing questions: you describe the practice you need and get a paper built for it, rather than picking questions one at a time.

Both of these do part of what Exam Builder will do, and both work today.
