Rep is short for repetition, the number of times you've practiced a given sentence. 

What are reps used for?

Reps are used to calculate and evaluate your learning progress: we adjust to your learning speed as you accumulate reps and progress towards fluency.

✓ Measure your learning progress
✓ Build up your muscle memory and confidence
✓ Improve your fluency at each stage

Reps help you achieve goals

We like reps because every learner has a unique experience. While I've studied French for a year might mean different things to different people, 50,000 reps is 50,000 reps. So long as you put in your reps, you will make progress.

That in mind, train in a way that works with your daily schedule and is at a pace you feel is sustainable.

Reps mark milestones in your language learning journey

Roughly speaking, here are the ballpark figures we've observed over time:

  25,000 Reps → Sentences roll off your tongue quite smoothly—the language no longer feels foreign to you
  50,000 Reps → Casual, everyday conversations are no longer scary
  75,000 Reps → Refinement: you're building the technical vocabulary you need to handle increasingly specific scenarios
100,000 Reps → Mastery: you can say pretty much whatever you want without really needing to think about it

(Note: We're referring here to cumulative reps throughout the course. For example, for a course like Spanish that has ~7,000 sentences, achieving 50,000 reps would mean doing an average of 7 reps of each sentence in the course.)
