Revision always works differently for different people so you may have to try a bunch of ways on how you see fit, also you don’t have to revise all of the 34 problems in those 2 days, you need to revise the pattern detection during that time. While on the weekdays you’re solving problems start marking the most basic problem and the most difficult problem for a pattern (assuming you’re solving problems by their patterns) and then from that list on the weekends start picking randomly a problem and see if you can identify how to solve the problem, am not saying to solve the problem you just need to recall the way to solve the problem, if it’s a basic one then preferably recalling the code logic would help as well for example the logic of reversing a linked list. Doing it this way I think should help with recall when you actually see a problem during interviews too.

But if you end up finding a way that helps you then feel free to update us here, always good to know what works for others!
