I am a non-major and passed with exactly 60 points after studying for one week. To be honest, I was too lazy to even finish one full round of past exam questions, but looking back, I think I passed thanks to these lectures. If you solve the "Yellow Book" (SQLD practice guide) while watching this lecture, it will be so difficult that you might lose your mind. For those whose priority is just passing the exam, I think it's better to solve all the past questions here and in other theory books first, and then only move on to the Yellow Book if you have time left. While it was good for catching concepts I missed, the Yellow Book is much harder than the actual exam difficulty... I think it would be great if there were more explanations connecting confusing concepts, especially for problems where the examiner is clearly trying to trick you, like those involving "Null."

Thank you for the great lecture.

I am developing a sense of practical application by listening to the lectures and watching the "Noraengi" (Yellow Book) problem-solving videos. As a non-major, I still have a long way to go, but I plan to take the exam by repeatedly reviewing the problem-solving sessions. The lecture materials provided are very helpful; in particular, running the practice queries myself has helped my memory, and being able to change various elements to deepen my understanding has been great.

The materials and practice exercises for the 2026 preparation are excellent!
