Maths practice for the advanced state exam: work by topic, by problem prototype, or just solve full papers. Russian curriculum, free.
Exam maths is a finite set of problem shapes, and the fastest way through it is to drill the shapes rather than read theory. This bot is built that way: choose a topic, choose a prototype — the recurring form a task takes in the paper — or take a whole variant and solve it end to end.
Practising by prototype is what separates it from a general problem set. When you have failed the same construction three times, working through fifteen versions of that exact construction is worth more than a chapter of explanation, and the bot makes that loop easy to run.
It covers the advanced-level maths paper of the Russian exam, so the audience is narrow by design, and the interface is Russian.

The recurring form a task takes across exam papers — same construction, different numbers. Drilling one prototype is drilling the thing that will actually appear.
The bot presents itself as the advanced-level paper, so treat basic-level coverage as unconfirmed.
