EDX can be used in different ways EDX can be used in different ways. I personally have used EDX since its inception. I am a huge fan of e-learning and wrote to the UK government 40 years ago when the internet started with the massive opportunity it presented to improve UK education - deaf ears of course (read Rory Stewart's book on how government does not work). But EDX and FutureLearn have provided significant resources for everyone in the world online and if you 'audit' the course (as I do) then they are completely free. Yes some vary in quality, but some of the courses I have reviewed are simply the best courses I have ever taken in my life - and I have a UK Hons Degree done way back when. So, I suggest people stop & think before paying - Audit the course FIRST - then, if it is good quality and is what you expect, only then pay if you really need a certificate.

Knowledge, Practical and Workspace Edx is a great platform to learn from, especially university programs. One course I took and loved was a computer science program by Havard University. The only challenge was that there was no workspace or platform to practice or code-along with your instructor. It would be great if such improvements were made.

Avoid!!!! Teacher was impatient with students and unprepared to start the course. He didn't have a formal coding education and he quit two months into the course. They do not provide a textbook version of the curriculum. They refer you to other people's work. I'm in the process of getting a diagnosis for auditory processing disorder and I was begging them for months for help and they refused. Repeatedly. I then suffered stress related syncope and ended up in the hospital. They removed me from the course but want me to still pay them $8,000

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.

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.
