Terrible would be saying something nice. Coursera courses are short, terrible and uncomplete. But the worst offender are their quizzes. WTF?! They got nothing to do with the course content and everything to do with semantic and saying a very specific word that might not even be in the course, since this quizzes are AI generated. Terrible. Coursera has zero support, maintained by a bunch of retarded developers that might have though too good of themselves by adding AI in their quizzes. DONT WASTE YOUR TIME
