Welcome — glad to have you here! Let's work through the unit circle and exact trig ratios together.

Practice & homework

Keep practising after the lesson ends.

Finish a lesson and a homework set is already waiting — built from the exact skills you slipped on. Or generate your own set any time: target your weaknesses, keep it balanced, or go full exam-style. Every question is graded against the real IB markscheme, with the working shown when you miss.

Progress & weaknesses

Always know exactly where you stand.

Every graded answer updates your mastery — by topic, by skill, and across three dimensions of understanding. The platform surfaces your weakest skills and quietly steers your next questions toward them, so your practice always lands where it actually helps.
