I'm writing this review before I've completed this course, to let you know how it doesn't work with the Firefox web browser. This program will force you to use Chrome, and while Coursera recommends Chrome to be used, it's pathetic that you can't use this course on any browser. For an IBM course where you're paying for two subscriptions that's an even bigger insult because I can't use Firefox. If you can, avoid any course that won't work across all web browsers.

this is a good course however the presented speak relatively fast and very little graphical presentation is done during courses. Students needs to see contents such as slides, text, images during presentations and not the presenter, there is no value in seeing someone talking.
