学生对 伊利诺伊大学香槟分校 提供的 IoT Communications 的评价和反馈

Of all the courses and specializations I've taken through Coursera, by far, this is the worst. Specifically, it has consisted of poor product selection for the course, glitches, and extreme delays. A more reliable product for the cost should have been selected. The wifi car is poorly constructed and unreliable. Additionally, trying to find technical assistance for it on the web is difficult if not impossible. In another instance where there were glitches with Coursera's site, I submitted a dropbox link for a peer review, but was told by a peer that somehow the link was coming up as a google link signed in as someone other than me. Finally, because of a lengthy time for peer reviews to take place, I was charged an additional month for a course that I'd completed 3 weeks earlier, except for the peer review requirement.
