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.

An challenging course but I think they go too too fast in the queries, because at the begginig its almost easy for a noob, but in the last week with the subqueries it was too too hard for me to understand what I have to do.

The course is well structured and it really brings you from inertia to coding in SQL (even if not in a high level). I'm more aware now of the relationships by using subqueries and joins, and this is certainly an up.

There are great practices but I don't appreciate the fact that once we are done with the exercises, we are locked out of it. I would definitely have preferred to go back and revisit and refresh every now and then.

Excellent course. the assignments are really challenging and require actual practice at real world problem solving. there are some mistakes in the course materials that took me some precious time to figure out.

The actual amount of time required per week to complete the course was well over the 3-5 hours/week advertised on the course homepage. It was a very time intensive activity each week- especially the last 2 weeks.

The course is great. There are a few problems with Terradata. I think if they offer an extract of the data in spreadsheet form, the problems would be much easier to work with. Overall, the course is good.

A very well designed course with no prior knowledge assumed. The discussion forums are very lively and queries (no pun intended) are responded to fairly quickly. A great option who wants to learn sql.

Very good, detailed course, I can recommend! Before that I knew nothing about SQL, now I have moved to higher level of analyst. Sometimes the instructions are not 100% clear, but it is minor problem.

The notes are perfect! But I do think that the content might be a little bit easy.. Good course for beginners, but if you are looking for more challenges, this might not be the best choice for you.

Its a very good class to learn to use SQL in a systematic manner, even if you had used SQL or are completely new. The two Databases ( Terradata and Dognition) gave a lot of valuable practice.

It's a great course for beginners, maybe being deep into two databases isn't fruitful enough. Web pages like kaggle.com can give more examples, more interesting and with current data

Great SQL course. I think the course overall is well structured and let me stretch myself week over week. It's a little difficult to write long query in SQL scratchpad though.

Very helpful and good course. The main focus is on the practice. There are many exercises which help to practice which in turn helps to understand the concept more.

The course is great , teradata login gave some problems thou , would have been good to have sample data and play around rather then a seperate login for teradata.

Great course with nicely designed practice questions. Would be even better if there is more help or sample answers provided for week 5--it is very tough!

Great course. Gave it 4 stars instead of 5 because I wish it had more video instruction as opposed to documents. I find videos a lot easier to learn on.

It's pretty good for entry-level SQL learners. However, to further improve, much time is required. Also, exercises provided are sometimes really weird.

Really good course for beginners, expected more video content. But overall the exercises and quizzes were very helpful in understanding the concepts.

This is one of the awesome course that I studied. A tutor is also very nice she has good knowledge of the subject and hands-on increases my knowledge

Challenging course going from very basic to quite complex SQL queries. Definitely recommended. The only downside are the repetitive technical issues.

great course.. only thing is answers to teradata exercises were not provided. So student cannot know whether he is writing correct sql statements

Very challenging, learned how to write very complex SQL queries. Be prepared to work. This is a 5 week course that took me 9 weeks to complete.
