Content

Starter pack v1 (1.0.0, 2026-10-30) was written for this site. It is self-authored, not yet pedagogically reviewed. It contains 15 grammar lessons, 298 objective items, 220 vocabulary cards, 12 reading passages and 12 workplace scenarios. If you find an error, treat the answer key as a suggestion and use “Dispute” on the Progress page.

No score on this site is a CEFR level, an exam prediction or a fluency certificate. We do not judge accents.
