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.

Bad customer service I have used the chat to ask questions about the course and the person (should've take the name -_-) on top of taking ages to reply, kept on telling me to "google it" , she/he clearly didn't know anything about the course (Front-End web dev). Now seeing all the bad reviews of this platform I will not proceed to the course.

Good freemium Good freemium Nice courses, a bit too informative but with a little bit of practice. I started the LLM course and noticed that, the business is inside the databricks workspace you need to purchase! Everything needs money, so even this course does it! It is just hidden behind a (necessary) condition to use the (payable) databricks workspace in order to make experiments with python code using LLM stuff.

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.

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 ;)
