From what I remember, there weren't any obscure formulas that I needed to use - just the basics. They'll give you constants if you need them, and I remember a couple of my problems having diagrams.
Also, keep in mind you only get a calculator for the QR section, so any calculations you have for the physics section (or chemistry sections) will have to be done in your head or on your dry erase sheet. If I were you I would spend the last week practicing problems without a calculator. When you're doing practice QR problems use the basic 4 function Windows calculator on your computer because that's what you'll get on the actual test. Good luck!
