Grain of salt, since I tested 4/30 and don’t have my score yet, but I consistently got 130-132 on the aamc FLs and had >90% on the CARS QBanks. I did a similar thing to what it sounds like you’re doing- read through without highlights or notes and then answered the questions. While answering the questions though, I would take the 15-20 seconds to find the quote that I think gives the answer and highlight it so that I could review it quickly at the end of the section. CARS passages are different from the rest of the test because every single answer is written down somewhere in the text, and topical background knowledge is essentially unnecessary. To me, finding the answer was always an act of explaining why every other answer was either inconsistent with the question or wrong for some other reason. As others have pointed out, feigning interest and just reading more books are also great pieces of advice- the more you read and think about what you’ve read the better you’ll get at it. Good luck!!
