Did Manhattan prep books for quant and verbal first along with OG guide questions. Then did target test prep for quant. Studied everyday for 1.5 months.

Took all the practice tests at the library, just couldn't take them at a time similar to actual exam. Exam was at 3:30 on the afternoon I have my practice exams in the mornings usually.

Really not sure how to proceed here. Really need a 750 to have some chances of getting into the school I want. Plan to retake it in a couple weeks but what should I do in between that time. I'm pretty sure I messed up SC and RC on the exam. I usually get all my RCs correct but there was one on the exam I just wasn't able to comprehend fully. First time that's happened. But how should I focus my next 2 weeks so that quant gets back to a 49-50 and verbal ofcourse needs a lot.

Have been really disappointed with myself and woke up at midnight worrying about this. So decided to reach out and ask for any advice. Would appreciate any advice or resources that will be helpful. Like a crash course on SC or something

Thank you.
