ACT practice tests are available at the websites PowerScore.com and 4Tests.com. PowerScore.com provides links to official practice tests from the ACT. 4Tests.com offers unofficial practice tests aimed at replicating ACT-style questions. The ACT replica tests are created by Barrons Educational series for English, mathematics, reading and science.
Another resource for ACT test practice is the website ACTStudent.org. The site features practice questions in all four traditional subjects as well as practice writing prompts. The site reveals the answers to questions, allowing students to gauge their progress.
As of April 2015, the actual ACT test is graded on a composite score of up to 36 points. Students are allowed to take the test multiple times.
