College Testing

Although the SAT and ACT are not required for admission to Arizona's universities, you should definitely make taking at least one of the tests part of your plan to attend college. These college admissions exams can be used to place you in your math and English courses for your first year, can provide more information if your application is not as compelling, and is usually required for most scholarship considerations.
ACT
The ACT is the statewide high school achievement test in Arizona and therefore may be the most familiar test. The ACT tests students' knowledge in English, Mathematics, Reading, and Science. Students can earn up to 36 points in each section. The overall score is calculated by adding the scores for each academic content area and then divide that total by four.
The ACT is typically taken in a student’s junior/senior year. Testing advice is available on the ACT website.
SAT and PSAT
The SAT is a standardized test created by the College Board that can gauge a student’s college preparation. The SAT tests students’ understanding of two subject areas: Reading/Writing and Mathematics. Students are able to score between 200-800 points in each section. The scores of both sections are added together and the resulting combined score is the overall SAT score. The overall SAT score ranges from 800-1600 points.
The SAT is typically taken in a student’s junior/senior year. The College Board offers Practice and Preparation for the SAT on their website.
The PSAT is the Preliminary SAT and serves as a practice for the SAT. Scoring high on the PSAT can also qualify a student for the National Merit Scholarship Program. The SAT is typically taken in a student’s sophomore year. Preparation for the PSAT is also provided on the College Board website.
Khan Academy
Khan Academy has a College Admission section of their website and also provides an overview and some study materials for college entrance exams. You may also decide to take some time to brush up on your academic skills by reviewing their courses.
