I scored 50 on my last one in july and 91 today, I am hoping its not a red flag- it shouldn't be. I took 11 hours of upper division courses and had a part time job while studying for that one.
Well when i took it in july i noticed there were a lot of calc problems- like derivatives mainly and stuff like that- so i studied that stuff a lot. I mainly used collins and just did all of the QA tests, and reviewed the questions i had no clue with in princeton review book. In collins i missed on average 25 questions- i was not confident about that at all (i finished those like last friday). But i reviewed the questions i got wrong and on test day i went in with the mindset that i was prepared and i know all the material. Never started thinking negatively like i was doing bad or anything, until after the test i thought i might have barely edged 70 comp walking out... haha just stay confident while taking it. If there are any QA questions you're really troubled with right now, focus on those even if its not working them out, seeing the questions and the types of answers that are correct i think helped me with guessing on several questions at the end.
when you get to that 15 minute break-
TAKE AT LEAST 10 MINS OF IT. I sat in the waiting room area staring at the wall and relaxing and not thinking about the test at all. haha sounds weird but it was really relaxing and i believe it helped me finish without being brain dead on quant..
GOOD LUCK! You all got this!!!
