my first MCAT prep involved reading TBR books. I took really good notes as I try to understand and memorize every single detail in those books. Unfortunately, I gave myself very little time to practice those amazing passages. I thought that as long as I read and understand everything in TBR books, I'll be fine. Boy was I wrong!
For my retake, my notes really helped me cut down the time I spent on content review. I realized that i had a good understanding of the material but not the practice to apply all my knowledge. So my retake prep was 70% practice, practice, practice.
Also, don't use TBR bio books. they give you too much info. The Bio passages are gold but reading all those long chapters with so much details is not something I would recommend.
