The ACT is designed to test your skills in English, mathematics, reading and science reasoning, and the exam includes an optional writing test. The four main parts of the test are marked with a maximum of 36 points with a composite score of all four, and the tests act as an assessment of your high school achievement. However, different colleges place different levels of importance on the results of these tests and often they will be taken into consideration along with your class rank, grade point average and extracurricular activities.
