Hi,
I am have been using Leetcode regularly for the past 1-2 months. My question may seem kind of stupid, (sorry if it seems so). When I am not able to solve a problem within a certain time limit I set, I look up the solution in the discussion forum and make a note of that question. My doubt is, how often should I look at these questions whose code I looked at from the discussion forums.

For example, If I solve 7 questions on a day, (5 on my own and 2 after looking at the discussion forums), how often do I review these looked up questions. Do I look them up at the start of the next day or once every week? And with this occuring everyday, let's say I have 10-15 questions that I looked up by the end of a week, is there any effective way to revise these questions?

Any help would be appreciated. Thanks!
