It Depends!
Some schools are test optional -- which means that you do not need to submit test scores if you feel that test scores do not accurately reflect your academic abilities! For a list of test optional schools, please go to www.fairtest.org. Many public state schools weigh test scores quite heavily -- almost on par with grades in college prep courses! Still other schools -- really try to look at the totality of your application and view your test scores as just part of the entire picture.
