•The course was well-structured, informative and easy to follow. One suggestion for improvement I have is that a cheat-sheet or catalogue of sorts be provided within the course, which collates all the coding and syntax from the course onto one single space.
This is especially helpful while taking up the course as part of the specialization series. It isn't easy to remember precise code syntax after just one or two uses of a function. As I progressed through the courses in the specialization, I found myself having to return to previous courses and comb through the hands-on labs to retrieve specific codes, functions and syntaxes. This was time-consuming and wasteful, and can easily be remedied by a list of codes (with syntax) used in an entire course.
Apart from that, great effort by the team, and a big thank you to the creators, developers, moderators and testers!

•I would put this a 3.5 instead of a three, but there is no option for that and i do not think it is a 4. The main problem with this course was that they threw at you a lot of complex concepts, functions and operations without letting you practice. Then, at the end, they put a practice lab in which you have to wrap up everything which you have learned, evidently, given the fact that this is a lot of things, you have forgotten things already. Also, there are some things that they never explain, for example the command sqlSave was never mentioned in the videos, and appears randomly at the lab. In the end, you can learn a lot of things with this course, but from week 4 and forward you will have to put a big autonomous effort to understand things correctly. Week 1 to 3 are ok, though week 1 and 2 are somewhat redundant

•The teaching part is not so good when it comes to teach how to install the drivers and create a connection and the project part is the worst of all the staff doesn't seems to care and give a reply to your errors or problems and it takes a lot more time to get it graded....really a bad experience with this course won't ever recommend this to anyone
