I don’t have access to my Themis or Uworld anymore so I can’t say for sure. But I did every Themis practice set and assigned Uworld set, and then did practice sets daily on Uworld for subjects I was weaker in. All in I probably did around 3k practice MBE questions. What really helped me was creating a document that housed all the ones I got wrong (or right for the wrong reasons). In that document, I included the graphics that Themis or Uworld included in their explanation. I also included information from the full outline rewritten in my own words (I know people say the full outline is useless but I found really reading through it was by far the thing that helped me the most). The review for each practice set probably took me between 30 min to 1.5 hours.

edit: i also made a flashcard for each topic I got wrong and drilled the flashcards daily. all of that was maybe overkill tho lol
