Practice that adapts to exactly where you are

Free to start · Instant explanations · Accuracy tracked per topic
Smarter than a fixed question bank
The test thinks while you think — calibrating difficulty, explaining answers, and keeping score by topic.
Targets your level
Get a tough question right and the next one steps up; miss an easy one and the engine eases off — so you are always practising at your true edge.
Instant explanations
A clear, worked explanation appears the second you submit an answer — no waiting for the end of the test to learn why.
Accuracy tracking
Every answer updates your topic-level accuracy, so you can watch a weak chapter climb from shaky to strong over a week of practice.
Never runs dry
Fresh, exam-style questions are matched to the topic and difficulty you need next — practise the same concept ten different ways.
