    Loved this course. I already knew the subject matter so this turned into a refresher course for me. It also gave me a few more nuggets of information as well, such as the order "HAVING" is executed AND finding out "HAVING" and "WHERE" can both be used in the same query. Really recommend this course.

    This is a very accessible and pretty extensive (albeit at times slow-paced) course, with good learning outcomes.

    The format works just fantastically well for me. The videos are short and the exercises really help to understand better. AI feedback is also useful. I like the final exercise at the end of each chapter that combine all concepts.
