Work at your own pace.
The plan length helps choose how many problems to include. It does not end your session automatically.
Adaptive Curriculum — BetaFocused practice,
Focused practice,
at your pace.
Training Lab creates a short practice plan from your Codeforces activity and the preferences you choose. The displayed time is an estimate, not a countdown, and plans remain available so you can return later.
Using a plan
Three things to know
Tell us how each attempt went.
Your result helps shape later practice. Codeforces sync checks submissions and accepted solutions.
Hints and editorials are context.
These notes do not mark a problem solved or failed. Saving or skipping also makes no mastery judgment.
Labels
Challenge labels are guidance
Confidence, Productive, and Stretch
These labels indicate the intended level of challenge, from familiar practice to a harder attempt. They are estimates and may be wrong.
No performance promise
Training Lab is a beta practice tool. It does not guarantee availability, contest performance, rating growth, or a particular result.
