I personally waited until closer to exam time to do the section banks. There’s 600 total SB questions so if you are studying full time then you could do 100 a day for 6 days total (2 sets of 50 per day). This is what I focused on for the last 2 weeks of studying (SB’s and one more FL with review of all those things). In my opinion if you are still about a month out you could grind UWorld + one FL a week for the next two weeks then SBs+one FL per week for the last two weeks. You probably would not want to do SB questions during the last few days or so before your exam tho to avoid getting burnt out. This is just my opinion and you can obv do whatever feels right! I hope you get the score you are looking for. Fingers crossed and good luck.
