Too theoretical.

The questions on the final exam where you need to right SQL code not related to the database you create are completely broken

Too many mistakes and typo everywhere.

good course

Waste of time. The readings are each a hodgepodge mess. The videos are repetitive and many are just of an actor talking. It's full of definitions, no visual representations. No guidance on setting up and using your own DBMS which it will randomly tell you in module 4 to use out of the blue with no clear instructions as to how. The Module 4 quiz tells you to use Coursera's MySQL database but doesn't link to it. The readings and final quiz have multiple typos and grammatical errors. It was all bad. Using Udacity instead.

Getting errors about needing to upgrade to new versions of courses. There is no note/option to upgrade per the support article. Coursera should do a better job with giving more detailed support info. Other then this issue, which has happened to me for a couple specialization, no complaints with Coursera. However this a major inconvenience. When the error message pops up about needing to upgade, why not take the user directly to the place where they need to do the upgrade?

Final graded quiz has mistakes. Plase check questions 2, 3, 6, 7, 8, 9 and 10. Plase read course forum you'll see a lot of students waiting for your attention.

Schlechte Übersetzungen und Fragen dazu noch oft schwammig formuliert. Manchmal kommen Fragen zu Themen, die erst später erklärt werden.

I'm having problems and have no one to reach out to.
