Honestly edX is my favourite site to do… Honestly edX is my favourite site to do these courses. The fee you pay for the certificates if you go that route are indefinite, so you can do the course as you please. Other sites you would have to pay monthly and depending if you don't complete within the month you'll only pay more. So, price wise really good. The courses I've taken are really well done. Quality instruction and depending on the course good forum interaction too. I've also done free courses and are exactly like the payed ones difference being the certificate. So, if you don't want to pay you still get quality instruction.

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 ;)

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.

Actual trash. Actual trash. They claim their concept is free education, with an added option to pay in case you want a diploma, but some of the courses straight up only offer you a THIRD of the course before asking you to pay to see the rest. Its a disgusting bait and switch one wouldn't expect from an enterprise touting about its ties to actual universities. Avoid at all costs. Also, the customer service is - as many have said - garbage.

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.
