It's a waste of money and time. Except for the occasional small tip, it's just okay. The explanation of the C++ code is a vague one-line summary. And unlike the title, most of it is just processed with blueprints. You can never make your own game with this alone. And it's not that the tempo is fast, it's that the explanation is missing. Still, the value of the short Korean explanation is there... I wouldn't recommend this course to anyone.
