No, there are not any prerequisite courses. At a minimum, you need to have a bachelor’s degree from an accredited school or university. In addition, ideal candidates will have a strong mathematical or otherwise quantitative aptitude.
If your undergraduate degree is not in a quantitative subject, or if you did not take or do well in many quantitative courses, we recommend taking a for-credit math course (e.g., algebra or calculus) or the GRE. If you don’t have experience with online learning, we recommend taking one of our introductory CS courses, such as Computational Thinking for Problem Solving or Introduction to Python & Java.
