Of the courses in this professional data science certificate I have taken, this is probably the best designed one. The labs force you to think and apply what you learnt in the video and not simply make minor modification to example codes. By the end of the course, I have internalized some of the commands. Overall, the labs were rather effective at drilling the concepts into students.

Some of the labs in the second week were rather lazily written. Instead of asking students to practice what they saw in the videos, all labs should contain actual questions that ask students to apply what they have learnt to new examples and problems, forcing them to think about what they have learnt.

The grading system is also in need of improvement. Some graders do not seem to know what they are doing. Simply resubmitting the assignment can result in a drastically improved score simply because the first grader was marking down answers that were actually correct. Perhaps there could be multiple graders assigned to any single assignment and the average score taken, or something to that effect.

I​ found it had the right balance of sql coding exercises with clear and illustrtive practise task. Although I personally never asked a question in the forum, the answers to existing posers aided me well. I must say the staff were empathetic and their responses in the forum generally exuded this friendly spirit, which is very important to code newbies. It's a huge bonus to learn IBM's cloud service interface alongside sql through this course and I didn't find the application interface overwhelming as some of the tech firms offering, I still found it difficult to access different resources like the sql studio and jupyter notebook on ibm cloud and the documentation there wasn't the most intuitive. I would give a five star when these resource links are made easier to identify.

This is a great course and I particularly appreciated the integration with Python/Jupyter notebooks. As in previous courses in the IBM certificate program, the labs were the highlight. They challenged students to answer questions using real data sets. Going from start to finish - from sourcing and downloading data all the way to analysis - was very helpful in mastering all of the techniques.

A couple of sections felt out of place: in my opinion, the optional database schema topics could become a separate course of their own, while the section on joins deserved more attention. The lecture slides, with the pictures of interconnected tables, were a bit hard to read and could do with an upgrade. Overall though, great pacing, with easily digestible videos. Highly recommend.
