If your scores are going down I can definitely say its you being your own enemy, I posted the following elsewhere
The secret is be a really smart *******
Let me explain
Funnily enough ive realized that OVER-STUDYING CAN HURT YOU AS MUCH AS UNDERSTUDYING. The thing is during the MCAT, where you are drawing from all the various different facets of the subject, a good 95% of the problems are ultimately asking something extremely simple. With this though means that with too much information in your head, you can easily get the answer wrong. I'm finding I'm missing mostly questions where I question my gut and ignore some knee jerk reflexes, so I change my answer. The reason I change my answer is I start thinking of all the little intricacies and corollaries I know of my own knowledge. The text (this not an actual problem, just example) specifically said that the reaction is exothermic, but because I started thinking about inter-molecular bonding, buffering, and quantum physics, I convinced myself that it was actually endothermic, when the passage SPECIFICALLY SAID IT WAS EXOTHERMIC. A real example is a problem that kept me away from a 15 on physics. The passage gave me a value, then asked for that value, I convinced myself it was 1/2 of that value becuase I started bringing other elements into play.
At the end of the day we must remove the idea that the mcat is trying to trick us. It is not. Ultimately the MCAT is a very difficult, but fair test. A person with good general background knowledge should be able to get a 11-12 on the sections.
Occasionally there are those dingus problems that require super-specific details and try to trick you, but they are few and far between. Their existence is to separate a 11 or 12 from a 13-15. If you are shooting for mid-30s, these should not worry youv
