Which test is right for you?
The SAT tests problem-solving ability. The ACT tests mastery of high-school curriculum.
The SAT is divided into 3 sections: Critical Reading (multiple-choice, 70 minutes total), Writing (multiple-choice and essay writing, 60 minutes), and Math (multiple-choice and grid-in, 70 minutes). Every correct question is given 1 credit, blank answers are given no credit, and each incorrect answer is less 1/4 credit. Each section is scored from 200-800 points, so the maximum score possible for the entire test is 2400. There is also an unmarked experimental section, which does not affect the final score.
The ACT is divided into 4 sections: English (multiple-choice, 45 minutes), Mathematics (multiple-choice, 60 minutes), Reading (multiple-choice, 35 minutes), and Science Reasoning (multiple-choice, 35 minutes), plus an optional Writing Test, which is a 30 minute essay test. Every correct question is given 1 credit, there is no deduction for blank or incorrect answers. Each section is scored from 1-36 points. There is also a composite test score that is an average of the four scaled scores from 1-36 points.
The ACT test is not as dependent on vocabulary and is more dependent on knowing the content taught in high school. Thus, studies have shown that students with limited English proficiency, students with high GPAs, and females tend to do better on the ACT than on the SAT. There is a concordance table on the ACT site that shows comparable SAT and ACT scores.
My advice is to look into the details (e.g., format, structure) of both tests and see which one you feel most comfortable with. Then, take practice tests (in simulated test-taking conditions!) for both tests and see how your scores compare using the concordance table. Finally, register and take the test you will do better on based upon the practice tests.
