THE GOOD: The course material was high quality as usual: well done videos, plenty of exercise, external resources, hands on style and a lot of useful topics were covered. THE BAD: I don't think this course was well thought through from a purely didactic standpoint. I didn't always have the information I needed to follow new lectures or answer questions. Some came later in the course, which means the topics order is wrong. Some were never covered, like SQL IN. Sometimes I got the feeling that I was supposed to be studying those external liks, but then the estimated time for this course would be totally underestimated. That 1h of this course lasted longer than 1h from the previous is a general feeling I had. Maybe because the Google Analytics Certificate, this fifth course covered harder subjects that the previous, expecially SQL. First, that should impact the expected time to complete. Second, I don't think the vague definitions, loose rather than formal, hands on rather than theoretical approach used so far is enough for a topic like SQL. I would have appreciated a bit more formalism and a bit more theoretical context.

I think this course had it's ups and downs. It was easily the messiest of the courses so far because the instruction of concepts was all over the place. One moment your learning about one SQL function, then all of a sudden your introduced to like three other ones that have never been taught until like later into the material. The instructor also did poorly in teaching and explaining what she was doing for some of the SQL queries, especially in week 2 and 3, where she just types a SQL query out and done, without any explanation of what she is doing or why she is doing it. This was one of the courses I was excited about coming into the program, and even though I learnt a lot about the different SQL functions, I felt pretty disappointed in how it was taught. Kind of wished we had the previous instructor for the data cleaning to teach this course as well because she made it easier to understand and actually went through the step by steps of different queries.

Only one so far that has a bunch of mistakes that was fixed after the fact with text. I know you are trying to follow the script and just powering through but seriously. Either reshoot your video or just fix the mistakes right there is fine. I alreayd know sql and this is making it so confusing.

There are a lot of new concepts introduced in this one and they can be more confusing for people with no sql experiences. It might be a lot clearer to just run everything through again. Also it is ok to go back and forth or even bottom up in some cases. At a lot of points the instructor is referencing "AS shorthands" before they were created. It was again very confusing. It is the internet video length shouldn't be a problem. I suggest you watch how harvard's cs50 professor Malan explain harder concepts to complete beginners.

I was expecting this course to train me in order to make analysis by myself in order to answer specific questions, and I finished it without having gained that skill.

This course is really useful in order to learn advanced functions from spreadsheets and SQL. Nevertheless, I think is too guided when it comes to actually performing analysis in order to answer questions: Most of the hands-on practices directly show you whats the SQL you have to apply or the steps and formulas to use in a spreadsheet in order to answer some question.

I would have liked to find challenges and practices where the course presents data, ask some questions and the student has to use the gained skills in SQL and or spreadsheets in order to answer it, without any guidance.
