Three doors this vocabulary opens.
French naturalisation requires B1, proven through TCF or TEF; DELF and DALF open universities. All of them are, at their core, vocabulary tests with grammar on top.
An official language in France, Belgium, Switzerland, Luxembourg, Canada and across three continents. The workplace words are their own topics: office, healthcare, law, IT.
French points are the fastest lever in Canadian Express Entry — and TEF Canada rewards exactly the broad, retained vocabulary daily repetition builds.
Every CEFR tier you reach earns a verifiable certificate with a public serial — retention checked at 7, 30 and 90 days, not crammed.
Specimen. Real certificates carry a unique serial and a public verification link; the Sealed mark means recall was re-verified 90+ days after learning.
Built for recall that survives the exam date.
Native-quality audio on all 6,300+ French words — tap the speaker on any card, or let the reveal read the answer to you.
Answer "voiture" when we asked for "automobile"? Accepted. French answers are checked against curated synonym sets, dictionary-verified — no red X for being right differently.
Every clean answer banks Tetris pieces; every miss costs a garbage line. The break between words is what moves them from short-term to permanent.
Download your topics and keep practising on the métro, the plane, or anywhere the Wi-Fi is not.
Five minutes today. B1 is roughly a year of days like it — and every one of them is checked, spaced and sealed.
