I finished 3 courses in 3 months in the IBM cloud platform course. I was delighted to only pay 39 dollars for each course. Its expensive compared to competitors, but the courses are on a good level for the price.Unfortunately the courses I did involved IBM Cloud. While working through my three courses I used many tools in the IBM cloud platform, was urged to create new ones, and with no strong warnings about the HUGE costs that would amass just by creating one resource duplicate etc.After receiving several expected "0 dollar billings" during my 3 months of doing the courses, now, 1 whole month after my last activity on the courses and having cancelled all coursera subscriptions, Im hit with a whopping 1350.5(before tax no less) dollars bill from IBM Cloud!To make matters worse, Coursera are completely uninterested in giving any assistance in the matter, basically telling me "good luck" without even a suggestion on making the dangers of the course more clear.The courses using IBM cloud are not bad, but they are a BIG economic risk, and coursera does not warn you what happens if you do not purge any accounts on IBM between each course.Im a bit dissappointed Coursera does not have a bit more foresight around external resources.
