As a college math tutor, the best advice I can give is to practice math and make an all-in-one formula sheet. I have done just that, this is a perfect formula cheat-sheet for those planning on taking intermediate algebra or for those who want a review of algebra formulas. This also works as a great study guide for when you are doing homework and preparing for exams.

Formulas include:
Properties of Exponents
Properties of Radicals
Variations
Slopes and Intercepts
Basic Geometry
Logarithms
And more
