It was great that the course included basic grammar and hands-on exercises, allowing beginners to learn by practicing as they encountered the grammar for the first time.

Because it focuses on solving problems, it stays with me for a long time. Thank you.

It’s such an honor to be able to take such a valuable lecture for free!

I’m preparing to become a data analyst. Although I learned SQL at school, I had forgotten most of it while working on certifications and other things, so I decided to take this course. It was extremely helpful because you taught us various practical tips, such as everything from the basic syntax to how SQL is used in the field and how to study it on our own. In the problem-solving sections, I tried to think things through and organize my thoughts as much as possible, write the query first, and check the results. When I really couldn’t figure something out, I looked at the instructor’s query, compared it with mine, and made corrections. I feel like this helped me develop my problem-solving skills. I’m still not familiar with WITH clauses and date functions, but I’ll keep practicing and improving my skills! Thank you so much for creating such a high-quality course and sharing it for free. I’ll also work hard on the practical application course.
