SAT Math is unlike any math test you've taken before. It's designed to take concepts you're used to and make you apply them in new (and often strange) ways. It's tricky, but with attention to detail and knowledge of the basic formulas and concepts covered by the test, you can improve your score.

So what formulas do you need to have memorized for the digital SAT math section before the day of the test? In this complete guide, I'll cover every critical formula you MUST know before you sit down for the test. I'll also explain them in case you need to jog your memory about how a formula works. If you understand every formula in this list, you'll save yourself valuable time on the test and probably get a few extra questions correct.

While there are many different SAT prep books, they all have one thing in common: they all claim to be the best. How can you figure out which one will actually help you succeed on the digital SAT?

This guide will give you my recommendations for the best prep books for the Math section of the digital SAT. Some of these books are best for strategies and thinking through the problems, while others are best for practice problems. A few are geared toward top scorers, while some will help you improve a low score fast.
