Doing Math w/o Calculator

I'm starting to figure out when I need to take the MCAT, and as a weak math student, I am going to go ahead and figure out how to do math without a calculator before I'm up the creek without a paddle.

Edit: I should clear up that I want to be able to do it more quickly, with better accuracy.

Does anyone have any tips, methods, or resources they suggest?

Thanks

do a lot of MCAT practice problems in chemistry / physics and practice rounding, using scientific notation, and getting comfortable with functions like log10

Download the app QuizUp and keep taking quizzes in the Basic Math and Advanced Math sections. There's a ten-second time limit per question and competing with other users will naturally increase your determination. In a few weeks, you'll be golden.
