Got any advice to help with the math section of the SAT?
Yes: the best way to do well in math is to take as many practice questions as possible with original College Board or ACT materials. Students learn to recognize the pet areas of the test makers (e.g., functions and certain geometric shapes). There so often is more than one way to come to the correct answer, and students who prep well know that way before taking the actual test. If the student has his or her actual PSAT or earlier SAT book or report, he can identify which types of questions tend to be troublesome and seek help on how to tackle those questions when the time comes. I always recommend to students to practice for quality over time and, on the actual test, check work carefully if time allows. Sometimes the brightest math students make the silliest errors by doing work in their heads or misreading the questions.
