You can use SRS to schedule the review of problems you've understood how to solve.

Front of card: where to find the problem (e.g., book, page number, problem number).

Back of card: where to find a solution (e.g., solution manual, page number, maybe a personal notebook with cleanly written solutions, etc.).

I initially tried writing up the problem and solution in Anki, but that was too much of a hassle and realistically I'm not gonna be reviewing problems without the book in front of me anyway.

Same, I put links to online geography quizzes on the front and then record my times on the back (editing each time). I just put them in a separate deck I only do at the computer. I'm gonna add Leetcode links too I think.
