Speed Maths
In prelims the maths is not hard. It is fast. Three seconds per question, one number at a time, until the table in your head answers before the calculator in your hand would.

Eleven topics. 641 questions.
Every question is generated fresh, so the same topic is never the same drill twice. Nothing is uploaded and nothing needs an account — your scores stay in this browser.
The first number is how many questions a drill asks. The second is how many that topic has in total — so a repeat run is genuinely different.
How to use it
- Start at 10 seconds, not 3. The point of the first run is to find out which shortcut you do not know yet. Speed comes after that, on its own.
- Read the review at the end. Every question carries the trick that solves it — the base method for squares, the sevenths cycle, the parity rule. The score is the cheapest part of a drill; the review is the rest of it.
- Come back to the same topic. Each one holds far more questions than a single drill asks, so a repeat run is a genuinely different set, not the same fifteen again.
