Thanks for all of the support, guys!
In general I used a lot of TPR and EK for content review. TPR was good for learning and relearning concepts. EK was good for consolidating information because it's a lot more brief, and tends to connect the dots between many different concepts. I don't think that any one book includes everything that you can possibly be tested on in the MCAT, so it was helpful for me to use multiple sources. I watched a few Khan Academy videos but I really found myself preferring AK videos on Youtube – he has a really, really good playlist for biochemical lab techniques (which are heavily emphasized on the B/B section) and was the only reason I finally understood how kidneys worked.
I actually paid for a TPR Online Course, which was completely not worth it for me because I didn't have the time to attend the lectures (4 x 3 hours/week) as well as doing all of the reading and homework for the lectures. I think using Anki really helped me because even on days where I didn't feel like actively studying, doing my allotted flashcards was a form of practice anyway. For full lengths, I used NS and one EK in addition to the AAMC material. I found NS harder than EK (especially in the C/P section, which for whatever reason has a ridiculous amount of calculations), but it's also cheaper so I ended up buying 3 exams for $99.
For general tips, I would say that I wish I had spent more time reviewing the SBs. The B/B section bank especially mimics the harder passages that you will see in the real B/B section. I also think the Blind Review method of reviewing FLs is very helpful, especially in CARS and P/S. The tip that most reasonated with me is that there are two ways of getting to the right answer: (1) you can know the right answer right off the bat, and (2) you can determine that the other three answers are wrong. Often in CARS and P/S, you will come across questions that are like ???, but being able to cross off wrong answers and ultimately understand why the right answer is correct is very helpful come real exam day.
