It's surprisingly fun, and I can see myself growing incredibly quickly. This is by far the best course for actually utilizing and applying the concepts of C++ grammar and object-oriented programming that I learned from Mr. Ttae C++ or other lectures or concept books. The total lecture length is about 5 hours, which is short, but since it's all open-ended problems, it requires a lot of thought. It was a course where I could learn much more than if I had spent several hundred thousand won a month at an academy and gone for a few months.
