Most colleges require the SAT or ACT. Be sure to check the college's website that you are applying to to find out which test they prefer. Students generally take the SAT or ACT twice in during their junior year and once in the fall of their senior year. The test should be taken as soon as your math class is complete. For example, if you are taking Algebra 3 in the fall semester and are not taking a math in the spring, you should take the December and/or January SAT. If you are taking Algebra 3 in the fall and Calculus in the spring, you should take one SAT in January and another SAT in May or June.
