    This course is helpful especially for bigginers, because it focuses on practical skills, deeper explanations of executed SQL commands, and an engaging instructor.

    This is perfect for beginners as it is hands-on and allows you to practice SQL from the beginnning. The crime story line makes it interesting and is different from a business requirement which can be a bit boring. Well done!

    I had taken Walters SQL Essentials course which was truly excellent and built knowledge via a step by step process. This course was not as well structured. It began very slowly, and was more repetitive, than at the end suddenly jumped and the final solution needed various SQL ( joins, sum, count) which were not covered at all in this course but luckily I knew from elsewhere. Also the online practice editor referenced was not well formatted and you couldn't make the output terminal wider when you wanted to see more results on the page, you had to scroll down and across - should be an easy fix.
