Good content, poor navigation I took 4 courses in the last year. While the course quality is good, the navigation through the learning material is a nightmare. Please fix the user experience ;)

Guidelines are vague/wrong Guidelines are vague/wrong, no credit given for completed modules which then prevents the exam from launching. It's so unclear that it doesn't tell you that you missed the exam deadline - rather, the way it's written, made it seem the exam wasn't open yet to be able to write it. No help available. Terrible.

Bad learning experience I was doing an LLM course the labs stopped working for me might course and edX support said that's a problem with the staff delivering the course. The staff delivering the course responded with a scripted message the forum thread I started and then went dark.

I feel scammed I did a course on electromagnetism, 8.02.1x. I completed the first (electrostatics) out of 3 courses, and the materials and teaching staff were great. However, I prepaid the whole programme, and before I could start the second course they were all removed from the platform. I did not get a refund for the remaining two courses.

Lean Six Sigma Black Belt Certification I did my Lean Six Sigma Black Belt Certification in EdX and it was a good experience. You would reminded to resume based on the class category you requested if once a week, 3x a week or extensive. And at the end of every module there were exercises/exams where you will be given 1-2 x chance to answer correctly. So, it is best to take down notes to get the most of the course. So far, I was given the leniency I need to finish the course according to the time allotted. There were some comments from previous takers where they were asking for the certificate after part 1. As for my experience, I have my certificate issued after part 1. The experience was by far, good and I learned a lot.
