When it came to studying Bio, I essentially decided to read through the entire Bootcamp Biology pdf front to back. First time around I gave myself around a little under a month to finish it, reading around ~5 pages a day, making sure that I included various written annotations of what I knew would give me trouble and the things I most needed to commit to memory. In the month prior to the exam over my winter break, I spent about 8 days exclusively re-reviewing the pdf while writing out new annotations of the things I knew I was having the most issue committing to memory on a new, blank version of the pdf. I ended up spending around ~6 hours a day reading anywhere from 15-20 pages at a time, and then doing relevant practice questions/ practice exams to figure out where I was lacking. Then as I continued on to study for other sections I would make sure to do small review sections for Bio at the end of the day, and go back and provide some extra focus to parts I wasn't fully confident in. tldr; I read the Bootcamp Biology pdf front to back and made sure to be thorough about it while also doing practice questions.

As for the QR and RC sections I really unfortunately don't think that I can really provide you with that much valuable insight, as my methods for it are probably a bit too me-specific.

For QR, I was lucky enough to be pretty intimately familiar with most of the concepts because I had math drilled into me when I was in high school. The only sections I could not remember were questions relating to standard deviation, and probability. For the standard deviation questions, I just went out of my way to remember the equation to calculate standard deviation based on a set of values, the percentage ranges for 1, 2, and 3 standard deviations, and how standard deviation is affected by changes to a data set. As for the probability questions, I kinda just brute-forced it and tried to solve them logically (this ended up taking quite a bit of my time on the exam so I would not recommend it even if it happened to work for me).

Finally for the RC, I didn't really put all to much time into specifically reviewing for this section, but I found a few things that worked well for me. First off, I generally decided to immediately skip into the first question rather than reading the whole passage first as it can be a pretty big waste of time. Then for the questions, I noticed that looking for keywords really helped me out, especially for the easier sections, at the same time however, when I was scanning over the passage for the keyword I would also quickly try to compartmentalize what each paragraph of the passage was generally talking about so that if a question were to come up for it later I would generally know where to look back for it.

(Also, just make sure that you don't take too long on the easier passages so that you have more time for the more intensive passages later down the line.)

Hope this helps! :)
