edX is an important education platform edX is a great platform, with courses and programmes (and qualifications!) from top education institutions. I always wanted to study with Harvard and Cambridge but ended up doing my degrees elsewhere, so it was a great opportunity to experience their teaching too. Also excellent. Kind and helpful customer service too. Thank you!

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.

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 ;)

Thanks again Thanks again, was a pleasure ! The only thing that was really annoying was the material and there exercises in the machine learning that were broken all the times so you needed to keep guessing and hoping that it will work out in the end. So Please dear course providers in the future stay tuned to your published material and keeping up to date and get us hanging in there ... Thanks a lot !
