How these exercises work

These exercises are built on a research finding called the pretesting effect (Pan & Chua, NUS 2026): attempting an answer before you've fully learned the material — even when you'll likely get it wrong — strengthens later memory more than passive study, provided you receive immediate corrective feedback.

So: you'll be asked to guess, often without knowing. Wrong guesses are not failures. They're the mechanism. What matters is that you read the feedback after each item and let the correct answer land.

The pretest score at the end of each skill is not a grade. It's a private signal of what to revisit. Class itself is where the actual learning happens; these exercises prime your memory for it.

The XP system rewards attempts (retrieval), retakes (spaced consolidation), and daily contact (spacing) — the three mechanisms the research points to.

Choose a unit

Five units. One story. Four strangers find their place in a new language.

The story — five units, one arc

The course is structured as a single narrative across five units. You’re not just learning grammar — you’re living through a semester.

Unit 0 — Arrival. You know almost no one. Every introduction is a small decision: tu or vous? Every form requires you to spell your name. By the end, you’ve survived orientation.

Unit 1 — Getting to know each other. The strangers around you are becoming familiar. An international mixer is coming, and you need to say who you are, where you’re from, and what you do — in French.

Unit 2 — Daily campus life. Routine sets in, and with it the pressure of register. The same news told two ways: a formal email to your professor, a casual text to a friend.

Unit 3 — The virtual Paris trip. Your French teacher gives the class a project: plan a trip to Paris. Every skill feeds the final group presentation.

Unit 4 — The farewell potluck. The semester closes the way it opened — with strangers becoming friends, this time over a meal you planned, shopped for, and cooked together.

You don’t have to read the units in order — pick whatever comes next in your schedule. But the story is there if you want it.
