After completing the course, I'm giving it the top rating. This course takes a practice-based approach that I thought was missing from my SQL books. By practice-based, I mean even more practice than the "hand-ons" approaches used by most SQL books. Most SQL books just don't give the reader enough practice with joining, aggregate functions, and grouping; they move on too quickly to advanced topics like subqueries and window functions. To my knowledge, the only SQL books that use the practice-based approach are written for T-SQL and not for MySQL (for example, "SQL Practice Problems" by Vasilik).
