Probability strikes dread into almost everybody. Couple that with the fact that many probability questions are convoluted word problems so that even the most confident math-o-phile is quaking in her boots. But before we get to the dread-inducing question a quick rundown. The magical, make-your-life-a heck-of-a-lot-easier probability equation: # of possibilities you are hoping to […]

Series of numbers Sometimes the SAT will ask you to notice a pattern in a sequence of numbers. -3, -1, 1, 3, 5 These numbers form what are known as a sequence. The one above is known as an arithmetic sequence, because each number increases by a fixed sum. So if we were to continue […]

Every now and then, the SAT gets really diabolical and throws a coordinate geometry question without the coordinate plane. To make matters worse, the question is usually difficult to begin with—even if you had the plane. The key is to translate the information by drawing out a mini-coordinate plane. Remember, this is a timed test, […]
