Khan Academy. Finish a course, retake the course exam once a year afterwards, fill in knowledge gaps as needed. Doing this should keep all undergraduate math fresh in your mind.
- throwamon 5y agoI wanted to like Khan Academy, but the pacing of the exercises is so frustrating. They become too easy too fast and then it's an extremely repetitive slog of useless computations. I wish for a service just like them but with many more difficulty levels and less (non-spaced) repetition.
- lordgrenville 5y agoI recently came across brilliant.org, which I think aspires to be this. I didn't stick with it but it might be what you're looking for.
