It's cumbersome, but the AAMC content outline (google "AAMC what's on the MCAT") and look for the 128-page PDF that they post on their website can be another helpful source to gauge your mastery of the content -- it can be a useful exercise to go through it, rate your confidence on every bullet point, and then specifically study points you feel weaker about using Kaplan or whatever other content resources you have. This can help break you out of that dynamic where you just kinda go along with whatever's in the book -- instead, you want to get more active w/ the material. As you review, try to go beyond passive familiarity. A good litmus test is whether you could explain the material to someone else. Also, as you re-review content, try to focus on core principles -- not all facts are equally important.
Keep doing representative FL exams and review the AAMC materials carefully. Like..inside and out. Not just whether you got an AAMC question right or wrong, but try to understand why the right choice is right and all the other choices are wrong, try to practice the workflow of solving a question successfully (for example, where do you need to go for information, how do you use passage info, how do you set up and solve the equations if there are any, etc.). If you got a question wrong, why? What can you do to avoid getting that question, or a similar one, wrong in the future? Often the answer is "know something better," but it also often will involve adjusting your thought processes, etc.
These are just some ideas I mention based on my experiences w/ other people, but overall the idea is not just to do more of the same, but find a way to approach content review and practice materials differently from what you did the first time around. Good luck!!
