While anyone can enroll in courses, it is helpful to have some background in mathematics for certain topics. Each course page specifies the assumed knowledge, and some courses include a ‘Course Readiness Check’ to help assess your preparedness.
If you're still unsure, you can enroll and review key concepts as you progress through the course. The course team also suggests additional resources on the website and within the course. Teaching assistants monitor discussion forums and are available to help with any questions you may have. Keep in mind that you can audit courses for free and re-enroll in the next session if you decide you need more time to review supplementary materials.
