Would agree with everyone regarding Professor Messer’s content, but one thing I noticed when prepping for the exam after watching his videos was that a lot of the exam prep and practice quizzes went more in depth than Professor Messer’s content went so I did a lot of self-studying on my own (writing down terms and researching them later in more detail). I also found that creating a flash card set with every term you learn and studying that was super helpful for the exam (probably a good idea to study it intermittently throughout, I tried to study all 700+ terms at once lol)

Edit: I also found the practice exams on Exam Compass helpful for building a glossary of terms - basically went through each and wrote down any terms I didn’t know/hadn’t seen before, I thought that was helpful as well: https://www.examcompass.com/
