Each section is unique and requires a different tact to do well. The thing about the C/P section is that the material is very different from how it was presented in college courses, so many people have trouble adjusting to the style of the MCAT questions. To do well, you HAVE to master process of elimination. Their answer choices have a definite pattern to them, and once you realize this, the questions will feel much easier. This can only be achieved by do realistic questions and then thoroughly reviewing each question and answer, and I mean painstakingly slow analysis of their word choice in the question and each answer choice. Figuring out what they are asking is not always simple to do, and it comes with active reasoning and focused practice. You have to do AAMC materials, especially the section banks, so make that your top priority. I do not mean this to be promotional, so please do not take it this way, we just happen to be the source most people think is best for C/P. If you happen to have access to our materials, do all of our Phase 3 homework sets and for every minute you snd on the passage and questions, spend at least two minutes on the answer explanations. Master C/P test taking, not C/P content.
The B/B and P/S sections are more content-driven than the C/P section, so you will have to do some content review in addition to mastering test taking skills. After every FL you take, and before you grade the exam, go back to each passage and summarize what it was and what you needed to know. Then grade your exam and as you review the answer explanations, see if you did in fact recognize what was essential. No matter what your score may be, good or bad, as long as you are getting what is important from a passage, seeing the big picture, and able to understand their questions, then you are doing well.
