Whatever you do, don't panic in the quantitative section.
The adaptive format is designed to make you feel as though you bombed the section.
Just keep in mind, if you're getting hard questions, you're doing well. My questions got so hard that I started taking way too much time. I thought I totally bombed the quant because I had to guess on the last 10 questions, however, I managed to still score a 47.
From my perspective, if you're great at math, the quantitative questions will be much harder than what you'll see on Kaplan. Powerprep quantitative questions are way too easy.
Verbal isn't bad at all....and this comes from an engineer. Just take your time to get the first 10 questions correct.
Get enough rest the night before too.
Good luck and let us know how you did!
