Hello,
TLDR my exam date is in about a week and I could really use some help with strengthening my performance in the hard quant section. Here are my stats:
Powerprep 1 (last week): 161Q 167V. I missed 2 questions in Q1 and 4 questions in Q2.
Powerprep 2 (this week): 158Q 168V 
I missed 2 questions in Q1 and 6 questions in Q2.
I’ve deduced that my issue with quant isn’t a foundation problem: I just took all of the foundations quizzes and got 96% in Arithmetic, 92% in algebra, 95% in coordinate geometry, 97% in geometry, and 93% in data analysis 1.
I know I have the knowledge necessary to complete all of the questions in Q2, but most (if not all) of my mistakes in Powerprep 2 came down to not having enough time/rushing. It’s never an issue with not understanding the math, though I may have to play around with the word problems for a bit to figure out what they’re asking. It’s also frequently the case that I’ll jump into what I think is a good approach, realize a minute in that the approach was futile, and try it a different way.
Any study tactics to help me gain more confidence in that final section in 1 week? I am aware of the skipping strategies but I think ultimately my problem comes down to getting flustered, feeling rushed, and sitting there for 20 seconds with decision paralysis because I don’t immediately know how to solve a problem (this freaks me out because, obviously, I know I’m rushed for time).
