I wish I could give them a no star! And I also wish I read this page before giving them my money.I took Introduction to Data Analytics course. I've completed all the quizzes, spent all the time to complete everything to be shown in the end that none of it was done. Then someone from their "tech support" advised that this was a tech issue and it will be resolved. More than a month later, still nothing. No badge of completion, no refund. Forget about this platform and do not hand them over your money- IT'S NOT WORTH IT! I can think of many other ways of throwing this money away.
