In my opinion,
That's exactly the kind of thing you will see on mcat. Like you read some random passage and then you see some info that you may not really know at the top of your head. I pretty much am doing problems and content review from EK biol and then I'm going to do random passages in the EK 1001 instead of doing them in order because I feel like that's kind of cheating. I like the opportunity of the passage questions to tap into my random thought process by not doing the passages in order (ex. do number 3 then 50 then 24 etc.) because that's how the mcat is going to be right?
When I see something that seems unfamiliar or is stuff that I haven't really reviewed over, I just sit there and really think about what this piece of information could mean before I actually look it up so that I can exercise my critical thinking skills as much as possible. Sometimes, I go as far as making it up so that when I see what the right info is, I get to slap myself in the face. (Yeah, I go in front of the mirror in my bathroom and then WAM!) Hey, my lazy self has to learn this stuff "somehow" right? lol
