Practice is unlimited on the free plan — every free Question Set, Vocabulary session, the Daily Quiz and mistake practice, as often as you like, with nothing to wait for. Premium unlocks the Premium Question Sets and Test Sets, so you get all 12,000+ questions, and puts a crown on your avatar.

Your ability score updates from your real answers and maps to a CEFR band (A1–C2) with a sub-level (e.g. A2+). It's the same score across Grammar and Vocabulary, so your level always reflects how you're actually doing — never a fixed percentage or XP count.

A mistake is marked fixed once you answer it correctly twice in a row during practice. Fixed mistakes move to your Fixed archive — if you get one wrong again later, it reopens and goes back to your open list.
