You are welcome to enroll in any and all courses that you think will be interesting or helpful to your career. There are no limits!
EdX offers hundreds of courses and unfortunately at this time we do not offer course advising, but you are welcome to try any course by enrolling in the free audit track. There is no expectation that a student needs to complete an edX course and there is no penalty for not keeping up or completing assignments. You are welcome to participate as much or as little as you wish. EdX does not calculate grade point averages or keep transcripts.
You can search all of our courses in our course catalog.
