High Yield Med Review has been very helpful in putting the BCPS exam into perspective. From watch the lectures, especially on biostatistics, to doing practice questions and being in the study groups has super helpful. The practice questions are great at explaining why a certain answer is correct in case maybe you missed something while studying. I found the lectures for biostatistics to be extremely helpful so I can grasp the concept and understand the explanation. The study groups were a bonus! It gave me something to look forward to on Monday and Wednesday nights instead of dread studying on my own.
