I purchased all 6 official online practice tests and I got 750, 760, 770, 780, 770, 780. However, when I took the real test, I scored a 740, which was lower than I wanted. I know my practice median was 770 and they say it can be +/- 30, but I'd really like to be on the upper side of that range when I retake.
Specifically, on the real exam, I found myself struggling on reading comprehension (something that I've never struggled with on practice tests) - I was taking a long time to answer those questions, and the passages were a lot longer and the questions were more difficult than what I saw on the practice tests. Usually critical reasoning is the time-intensive part for me, so I can't afford to spend too much time on RC questions. Any suggestions would be great!
