I will tell you what I do:
Gen Chem: I relearn everything and learn some of the tricks I knew previously. Look at the equations every few days to see if I remember them to the dot. Although at times, I get lazy and say "oh I know that topic" and then when I do practice I fall for questions that are focused on nit-picky details. PS was by far my strongest section on the old test, I voided my old MCAT test but I do remember seeing a big 2-3 point jump about 3 weeks before my exam by reading the equations over and over on a daily basis. Memorizing them and knowing all the units.
Physics: Similar to general chemistry. I'm trying to understand certain topics that I really struggle with which are certain areas in physics 2 material. This used to be a hit or miss on the old test. I remember getting one or two wrong out of the 20-30 or so physics questions on one of the old AAMCs. On the old test, if the PS section worked in my favor I usually scored 2 points above my average. Right now I'm focusing on mostly my weak topics and all the relationships/nit picky details as well.
Biology: I remember after AAMC 3, my bio score was consistently at a lower score. I focusing more on reading passages more carefully and on discretes I make sure I completely understand every choice before putting down my answer.
Biochemistry: Right now I'm sporadic, sometimes I do great in it and sometimes I do poor. It needs more content review and practice.
Organic Chemistry: It feels like a lot less on the new MCAT. I think it's a good thing. I never thought the AAMC organic questions were bad. It wasn't one of my strengths.
CARS: practice practice practice.
Psychology: I remember a lot from the classes I have taken.
Sociology: My weakness in this section. I tend to have trouble applying social theories. Psych/Soc feels like straight recall and the passages feel like as long as you can reason your way through the answer choices, you should score well in this section.
