Revise what you solved

Most of what you solve is gone in a week unless you see it again. FleetCode brings each problem back at the right time.

• Day 3, day 7, day 30. Mark a problem solved and it comes back here three times, further apart each time.
• Your notes come with it. The trick you wrote down shows up next to the problem when it's due.
• Still hard? Send it back to the start. Busy today? Snooze it a day.

Only you see this. Nothing here is public.
