How important are your SAT scores? In a word, very. College admissions offices do look at the whole picture when considering you for entrance into their program, but a great SAT (Scholastic Aptitude Test) score would go a long way to offset a less than great GPA or extra curricular activity resume. Recently reformatted from a multiple choice test to questioning that demonstrates your critical thinking skills, the SAT remains the college entrance exam that most universities prefer. Here’s what else you should know:

1. It takes about four hours to complete. You will be tested on math, reading comprehension and writing. Some multiple choice questions remain from the previous f format, but mainly the test is comprised of problem solving and logical reasoning skills. There is also a short essay to be written in which you will defend a position in a clear and logical way. As you might guess, grammar and punctuation are of the utmost importance.

2. Preparation is very important. There are various workbooks and pre-testing courses available, some of which are very costly. Some students prepare months in advance by hiring a math or writing tutor.

3. Students generally take the test twice and submit their higher score. The end of your junior year and the beginning of your senior year are a good rule of thumb.

4. Although the ACT (American College Test) is gaining in importance, the SAT is still the most widely accepted test across the country.

Remember, if you don’t do well, you can always test again. Make sure you come in well rested with a clear head. Your SAT score is just one of many ways to paint the picture of who you are. You’ll also be providing letters of recommendation, your college application essay and a resume of community service and extra curricular activities.
