Probably I would give it a 3.5 if there was the option, but ok, let's leave it at 4. The reason is the way the whole course is presented, you go through all the videos and once you are done with them, there is a quiz and exams. There aren't any excersises between lessons taught in the videos, where the student can practice while the concepts are still fresh. For me that was not a problem since I have experience with SQL, but I could see someone with no experience struggling.
As a final comment, the final assesment have a big flaww: The instructions are not very clear. I am certanly not the only one that had a difficult time understanding what was expected... The biggest problem was related on the size of the data that is available for the final assignment. All is limited to 10K rows which means that when we try to join tables, for example a review on the users, not all the revies exist in the review table, but in the user table (review_count), we know that there are more reviews than what we can find on the other table. I have struggled with this because my approaches and desired analysis for the second part were not possible to realize

The course covered the basics of SQL syntax, key statements and operations and some use cases to provide examples. There was also good information about best practices and how SQL theory can be applied to situations you are likely to encounter at work. There were regular quizzes and mini projects to apply your learning and test your knowledge. I did like much of the final assignment however some of the questions were ambiguously worded which made it difficult to work out exactly was being asked of me. Also one of the questions in the last part was far more difficult than anything experienced up until then which made me believe it was out of the skill range expected from the course. The peer-reviewed nature of the final assignment was a good idea but does rely on the judgement of other learners rather than someone who knows the material extremely well. It would have been good to have a combination of a timed test as well as a small guided project to test all aspects of my knowledge. This is however a very good introduction to SQL and provides some idea of what might be expected in it's professional use.

Excellent course. Professor very knowledgeable and professional. A few minor observations -- the presenter could have broken down some of the larger topics (i.e. joins into separate modules and prepared more practice assignments, especially writing queries so the students could get more comfortable with the task. Also, the alerts when a students does not write a query correctly could be a bit more explicit (i.e. which"(" they are referring to). Furthermore, one of the questions in "Graded Assignment"in the Week 4 Module where the first question did not recognize one of my answers as correct, even though it was. Next, some of the questions in both the graded and final assignments were not clearly worded so it was a bit difficult to understand what they were asking. Finally, if I wanted to repeat or pause a portion of the video, it would often jump back on to the very beginning.
On the whole, however, this course was very informative, interesting, and enjoyable. A must for anyone interested in improving their skills in both data/database management and computer skills in general.
