So after each block, I'd read through every single answer choice description whether I got it right or wrong. I'd write little notes of ANYTHING I didn't know or thought was worth memorizing, and wrote it down in a notebook. I'd draw a line across the page under my notes when done for the day and write the next day's date. After I got a week or two into it, I started reviewing the old notes. I would do a block on UWorld, then review the notes from a week ago, then review the block I just completed and write new notes from today. Rinse and repeat. After reviewing old notes, I put a tally mark next to the date (each set of notes was dated) so I knew how many times I'd reviewed it.
If that description isn't clear enough, please let me know and I'm happy to clarify.
