SQLD Noraengi Problem-Solving Lecture Full Version!




"SQLD Yellow Book - why does it feel like you're stuck in place no matter how many problems you solve?"


If you're preparing for the SQLD exam, you've probably opened the 'Nolaengi (SQL Certification Practice Problems)' workbook at least once as essential reading. But the reality isn't easy.

I've prepared this for those who, even after carefully reading through the answer explanations, still can't resolve the fundamental question of "Why is this the correct answer?" and only feel growing frustration.

If you've had the experience of reading through theory books multiple times, thinking you know the content perfectly, only to find your mind going blank when faced with slightly twisted real exam questions, please pay attention!


Recently, the SQLD exam's question trends have been rapidly shifting away from simple memorization-based questions toward requiring deep understanding of data modeling and principle-based application skills for complex SQL syntax. In other words, it's now difficult to reach the passing score with just last-minute cramming.

Therefore, this course doesn't simply stop at a 'quick crash course' approach of pointing out the correct answers to problems,
but focuses entirely on helping you develop 'real skills' to see through the traps set by test makers and their intentions, and to independently break through the core knots of complex, intertwined problems.



"The most certain opportunity cost of finishing one problem book: an expert's guide"


Just as you would hire a veteran local guide to avoid getting lost in an unfamiliar foreign destination, the most important asset in the long journey of certification preparation is where you focus your precious 'time' and 'energy'.
The time spent struggling alone to create dozens of pages of wrong-answer notes and searching through communities to ask about problems you don't understand, waiting for responses, actually incurs a greater opportunity cost than you might think.

Leave that arduous and laborious process to me!
Based on data accumulated from producing numerous successful candidates over the years, I will systematically organize the core concepts that must be covered within the Nolaengi problem book. All you need to do is follow the efficient learning path I've prepared for you.

This course will be more than just delivering knowledge—it will be an economical and strategic choice that most reliably accelerates your path to passing the exam.



"I will be your supporter, giving you confidence on the path to success—not alone, but together"


Studying for certifications may be a lonely battle with yourself. However, I will be by your side as the most reliable pacemaker and supporter, ensuring that the frustration and anxiety you feel during the process don't break your passion.

I will instill in you the 'confidence' to solve problems with clear evidence, not vague guesses. Until the day you can face questions in the exam room with a smile instead of panic, I will pour all my know-how into being there with you.

The preparation is complete. Now it's time to prove it with the result of passing.


I'll see you in the lecture.

Thank you.
