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.

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 ;)

Auditing Ive audited several edX courses. I like to complete and submit work and know how I progressed, but I don't want a Verified Certificate. The last course I attempted - got half way through then - bammo - couldn't submit work for assessment unless I paid for a Verified Certificate. Come on edX. Tell us at the start of the course if auditing is going to be assessed or not. The course is most interesting (no complaints) and Im going to do the assignments, but I do like feedback.

I bought a $5 course on my favourite… I bought a $5 course on my favourite topic. When the course began, I could see a woman in large glasses in her own kitchen reading a course on the screen. I couldn't be disappointed more. Not in vain the program doesn't offer any refunds or excerpts from the course. My advice: Always trust courses that can offer a refund and can show some excerpt from the course before you'll pay for it.

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.
