Test prep is a very important part of the college admissions process.
Your test scores can be the deciding factor in admissions decisions as your score on the SAT, the ACT, or another college entrance exam is easier to quantify, compared to your other application materials, which can be more subjective than a standardized test. The test gives college admission counselors an objective means for comparing you to another applicant, at least on one level.
Test prep helps you pull together everything you’ve studied to date and measures your ability to apply that knowledge. Additionally, your test prep gives you a chance to sharpen your skills in math, reading, and writing. This in turn gives you the tools you need to deal with math and language arts on the next level at a university.
