ALEKS is a college entrance exam used by some schools to measure Math skills and knowledge. The test is adaptive, meaning the questions get more difficult as students continue to answer them correctly. Students are able to use the on-screen calculator with problems in which it appears. Depending on the college/university a student is applying to, students may be able to take this test up to 5 times. Before retaking the exams, students will have to log a total of 5 hours of practice in the online work area. Students will need to retain their username and password created when first taking the exam. Students' accounts will expire after 6 months.
