The goal of test prep is to learn tips and tricks that help maximize your time and performance on a college admissions test. Students are taught best practices for creating a study schedule, pacing themselves during the test, and using process of elimination to narrow down the answers. While not required, test prep can certainly help put you at ease on test day – and it is commonly correlated with higher test scores. SAT test prep could be free through online quizzes and books from the library to thousands of dollars for one-on-one tutoring.
