This is an easy, basic course for SQL aggregate functions. This is definitely for beginners and the instructor makes a few mistakes and uses some unusual contract examples. However, it was a quick, nice refresher and for those looking to practice aggregate functions, it covers the core topics well. I especially liked the provided sql scripts so you can quickly create your test databases and test on your own system using your SQL dialect of preference. This was my first time to use PostgreSQL and I enjoyed it. It has a few things I like better than MySQL. I like the latter and had it installed prior to taking this course. Thus, I won't be uninstalling it or replacing it but PostgreSQL is a great alternative.

Great course. Instructor moved at a good pace. There were several opportunities to work without instructor guidance and learned new skills. The instructor also pointed out a few nice little tips to keep in mind when working with aggregate functions.

It was a good foundation for a learner although I found he was less detailed than the Power BI course and I missed the additional exercises which did enhance my learning experience. But I would highly recommend this course of an SQL beginner.

Class was good. I couldn't find the answer to one of the quiz questions even after going back to the lesson referring to it.

A complete and easy to understand course on SQL aggregate function.

Instructor was very good and covered topics quickly and thoroughly

A good course to take!!

Very good project!
