I suggest taking the majority of your FLs within the last 32 days of studying. You should probably take another FL at the half way point in the content review and again when you're 3/4 done with the content. Once you reach the 32 day mark (should be done with content review), take at least a day off, two would be better. Next, alternate between a day where you take a FL and a day where you thoroughly review the FL you took the day before. As a side note, you should still be doing as many timed practice problems as possible.
Lastly, get two sheets of paper, rip off pieces and write down the MCAT PS & BS topics. Put the PS topics in one hat and the BS in another. Draw three pieces of paper from one hat and try to connect all the topics. After you do that, make up what a passage would look like in your head and what kind of questions you would expect. If you don't know how to connect the topics, review ALL three topics.
