It was great to get a feel for SQL as a first step toward coding tests and to solidify my foundation through this lecture. The instructor is the best!

Even though I already knew SQL, this lecture helped me solidify the concepts properly. It was great to organize the SQL syntax I had forgotten, and since it was categorized by problem types, I could focus on my weak areas and structure the different types of problems clearly in my head!

Thank you for the great lecture!

I also work as an analyst, and since the types of work requests are usually quite diverse, I used to spend a considerable amount of time planning analysis tasks, including report writing. However, this course has been very helpful in categorizing my work over the years. Also, the mindset you emphasized really resonated with me, and I was able to reflect on it once again. Although it's brief content, it seems to be a course that makes you think deeply and look back. Thank you for sharing.

I learned about what data analysts do.

Clean and good

I liked that the class was taught slowly. Your pronunciation was accurate and your delivery was excellent. Also, the way you conveyed the information was great. Each sentence was connected, so I wasn't confused and could understand in order. You used regular syntax, which made it easy to understand the overall terminology. I think even computer novices will now be able to understand the terms that engineers use. The lecture was so interesting that I studied it carefully and slowly. I'm going to review it again. I have confidence in computers now.

It was easy to understand Tableau because you meticulously taught us every detail! The lectures are short, so there's not much pressure!

You explain the basic content well with easy-to-understand explanations and examples. It seems like there is no better lecture for learning the basics.
