SHORT ANSWER

Return to learning material on separate occasions. Use a genuine recall attempt, check mistakes, and choose a schedule you can maintain.

The key idea

There is no single interval that fits every subject. Give a difficult idea another look sooner; revisit an idea you can explain after a longer gap.

A practical example

Keep a short list of the questions you missed, correct them from the source, and schedule a fresh attempt rather than copying the answer.

Keep the result checkable

Review supports remembering but does not replace understanding, application, or course-specific practice. Remove cards that no longer serve a learning objective.
