Problems are too basic and short. There also aren't enough examples. I would like if the instructor had gone into more detail when describing some of the less common functions and commands.

The title is complete lie. '27 Practical SQL Queries to solve Business Problems'? More like '27 VERY BASIC POINTLESS Queries'. This is the second course by Bluelime where my expectations were not met by a long shot. In this 'course', if we can call it that, the instructor goes over how to query data over and over again in the most basic and really not practical means for any business. The explanations are sub-par, and the techniques demonstrated can get you into trouble when they are presented with limited explanations. Do yourself a favor and avoid this course and ALL Bluelime Learning Solutions courses. I know I will.
