One of the best course till now I find on Coursera, well structured everything and practice questions made me feel like real life problems as data were from real database of dognition and ua_dillards.

Nice and well-organized course. I joined this course after self-studying on SQL for a few days. The context is really nice. The only problem is the Teradata is not stable. I tried very hard to login.

What this course can improve is it should adopt the habit of thinking more instead of writing. Because in the week 5, the quiz is much more difficult than all the exercises we have done in previous weeks. And we don't have the guide step by step like previous weeks. I do know we have a week 5 quiz guide. However, when you write queries, sometimes, you do think your logic is right and query is right, why can't I get the same answer with the choices?
And when I finish the quiz and look back to the answer, I even can't find the logic difference between answers and mine but the reality is I can't get the correct result. There is only one diff I have found in one specific question, that is, I didn't use the same format to define one constraint. But I do think my way is also fine and I also get an answer I think is totally correct from the logic.
So I do suggest the answers should not be single sometimes, you should consider some specific formats or situation when students write their own queries. Don't give simple answer, give the reason why you are correct.
