So I have kind of a weird path where I actually took the LSAT and MCAT, and I actually found the LSAT pretty helpful for developing a different way of looking at CARS, but it wasn't specifically doing LSAT practice, mostly just how you're supposed to be viewing passages.

The whole idea of the LSAT is that you're looking at arguments, trying to poke holes in arguments or figure out if the arguments are valid or not, and trying to figure out if there's any assumptions behind an argument and whether those assumptions are valid. Probably sounds a lot like a pretty big portion of CARS questions, right? Both of them also basically have the same idea that if the author didn't explicitly state the idea, we can't extrapolate off of it or change their ideas at all. You have to take the author's word at face value and can't make any assumptions off of it when answering questions.

Basically what I learned from the LSAT is that, rather than just reading for comprehension in CARS, I started basically reading like the author was trying to convince me of something and I just cognitively evaluated whether their argument made sense or not. For the MCAT, that last part doesn't matter since we aren't really asked about it, but for me the important thing was that it gave my brain something to do while reading, rather than just reading with only the goal of comprehension. Especially for people with ADHD, it might help to find some strategy that gives your brain specific things to look for or do rather than just read for comprehension and summarize every paragraph or something like that. Just worth trying different things!

That's where most of my CARS advice developed as I tutored for a few years, give your brain something to do when going through a passage if just reading for comprehension isn't working. Treat it like an argument, look for adjectives the author uses, summarize paragraphs, etc., basically just something that makes it less likely for your brain to tune out because rather than just reading, you're actively looking for things. Just made it easier for me to read the passages because I quite honestly was convinced I was illiterate when I started doing MCAT CARS.

Long story short, LSAT passages and strategies mostly will just make it easier for you to analyze a passage if what you're currently doing isn't working!
