I just took the BB and CP portion of the AAMC official guide. I feel like it is more helpful to understand the question types and style. Any other thoughts? I got a 70% on the BB and 60% on the CP
The AAMC official guide is a very great resource for you to use when you are studying for the MCAT. Be sure to use up all of the questions and don't worry about getting certain ones wrong or obsessing over percentages right and wrong. Some questions there may be tricky. What matters is that you take those practice sets blind and according to test timed conditions and thoroughly review answers that you get wrong by doing excel or written review sheets. Because the best way to improve is asking yourself what your thought process was when picking a wrong answer and how to change it to make sure you have the right thought process to pick the right answer next time.
