I am a major, but I have so much to study in terms of language and SQL that I chose this lecture while searching! The lecture content was easy to understand, and they gave me a separate theory collection at the end, so I was able to study the theory as well. In fact, the first problem of the 2nd practical exam in 2024 was exactly the same as the difficult problem in this lecture. I probably wouldn't have been able to get it right if I hadn't taken the lecture. For those of you preparing for the practical exam for the regular exam, don't give up and just listen to this lecture faithfully, understand it, and memorize it. You will definitely pass. I listened to it all night for two days and I think I will pass.
