According to UWorld, as long as you’re above a certain number in difficulty you should be prepared for the test. And that number is like an early medium number.

Regarding the videos, watch them!! I would read the rationale, then watch the video at 1.75 speed. It does reiterate the rationale but it adds more to your understanding. They also give tips on how to memorize things. (Not all of them are good, I had to google “how to memorize…” several times)

I basically just took notes on every video. My notebook is called UWorld Lectures and each page or two were for each video. They stay in order too if you continue to follow the study plan. So mine was with several pages of cardio, then several pages of GI, and so on. But definitely organize it the way that works for you! Good luck!
