AMERICAN COLLEGE TEST (ACT)
The ACT is an entrance exam used by most four year colleges and universities to make admissions decisions. The ACT has four sections: English, Reading, Math, and Science, as well as an optional 30-minute writing test. Some schools may require the writing test, so be sure to ask before you register for the ACT. You will earn one ACT score (1 to 36) on each test (English, Reading, Math, and Science) and a composite ACT score, which is an average of these four tests. The composite score falls between 1 and 36. The ACT is offered nationally every year in September, October, December, February, April and June.
