Exercices

Short, self-marking practice for the skills a level exam and a job both lean on. Every question is generated fresh, so you cannot memorise the set — you have to actually get quicker. Two ways to run one: free practice, where the streak counts how many in a row you get right; or Do 10, a ten-question session with a clock, a score, and a summary that names what you missed and lets you redo just those. Streaks and best-of-ten live in your own browser and nowhere else — nothing to sign up for.

Each card says whether you tap an answer or type a number, and about how long a session takes. The suggested order runs from the tape to the symbols; the trade math lessons sit beside the arithmetic drills if you want the method before the practice.

On paper instead

When a drill comes easily, prove it cold on a printable worksheet — twelve problems on Ohm’s law, voltage drop, series and parallel, trade math or motor control, with an answer key that shows the working. A new sheet any time, free.
