I've been doing Kaplan and Math Destroyer and I'm getting destroyed on QR. My kaplan class instructed me to use the calculator as little as possible and to approximate the answers (even though they have a calculator that simulates the real thing). I don't have a problem when the answer choices are reasonably spaced but a lot of problems have choices that are really close.
When should I be using the calculator and just punch in the numbers?
Does the calculator stay open or does it close after each problem?
