Anki FSRS explained: what it changes
FSRS is Anki's modern scheduling system. Its job is to estimate memory more accurately and schedule reviews around a chosen level of desired retention.
What FSRS optimizes
It uses your review history to estimate how difficult a card is and how stable the memory has become. The next interval is then chosen to balance retention and workload.
Desired retention matters
A higher target generally means more frequent reviews; a lower target reduces workload but accepts more forgetting.
The scheduler works best when you grade recall honestly. Do not press Hard or Easy just to force a preferred interval.
Review Again, Hard, Good and Easy and how spaced repetition works.
Use Anki with ready-made language content already organised by level.
