“more frustration inconsistencies in this program than I have time to address again. Let's start with the entire program and this course being inconsistent and thrown together cobbled from different courses all through ai videos which is mostly tedious and boring and are usually just surface material. the labs for the most part remain broken which should not be the case for a paid course. The program is way too long 14 courses with five modules a piece which is absurd since most of it is just repetition and module 5 does not need to be there. The final assignments are a disgrace when you AI can't even grade the content accurately giving you zeros for parts you should get full credit in etc. Another issue you have students that have not done the assignment just using one pic like of a car pasted over and over again and some with no filled-out content hanging on there for months?? Where is the Coursera staff to take care of this I don't get paid for it. Truely an awful learning experience and I have taken a few programs already I will stay away from all IBM ones in the future, Awful very awful tedious and broken over all with help from no one.”
Coursera's 4.7 comes from 74 ratings. Of those, 5.4% are 1–2★.
Starisk reads the reviews learners voted most helpful, and weights each by the square root of its votes: a review with 80 upvotes counts about five times one with 2. Unvoted reviews are not skipped out of laziness — by this model they carry no evidence that other students endorsed them.
That measures what the most-endorsed reviews say, not “true quality.” The rating distribution above is the whole population, so you can see the sample next to it.
