How the pathways work
Every unit is headed by a can-do statement — the thing you will be able to do once you finish it, written the way the CEFR writes them. That matters beyond tidiness: the CEFR levels are what TEF Canada and TCF Canada are built on, so "I can give a price, a date and a time" is a step toward a score, not just a topic you covered.
Steps are of two kinds. A lesson step you tick yourself when you have read it. A practice step ticks itself: once you have moved 60% of that drill's words into the "learned" box, the step is done. Nothing here asks you to mark your own homework on the part that can be measured.
Do I need an account?
No. There is no signup, no email and no payment. Your ticks and your drill progress are stored in your own browser and never sent anywhere — which also means they do not follow you to another device, and clearing your browser data clears them. You can see everything you have practised on the practice dashboard.
Which one should I start with?
Start with A1 unless you can already conjugate être and avoir without thinking. Go to A2 if you can, but cannot yet put a sentence in the past. The path for B1 assumes the passé composé, the imparfait, the futur simple and the object pronouns (le, lui, y, en). The path for B2 assumes the conditional and the present subjunctive, and opens with a unit on the TEF and TCF themselves.
If your goal is a Canadian PR score rather than a level, the number that matters is NCLC 7 in all four skills, and the tasks that decide it (persuading someone, arguing an opinion in writing) are taught in the B2 path. Check what your scores mean with the TEF/TCF to CLB calculator, and if you are aiming at CLB 5, read the 12-week CLB 5 study plan alongside the path.
