It was tough. I went in after finishing a basic book on C++, so I tried to listen to the first part as a review, but it was definitely not easy. The instructor's process of disassembling the assembly language and code in the beginning gave me a lot to think about, and I think it helped me a lot in terms of mentality when coding. I think the details that he gave me in the latter part about STL and modern C++ grammar are hard to find in other basic books. In conclusion, I recommend it to both beginners and those who are studying once and reviewing. If you are completely new to programming, you should prepare yourself and go in with the determination that you will have 2-3 times more time to think on your own than the lecture time. The lecture is detailed, so there is no part that you won't understand, but it will be difficult to continue to the next lecture, so start with the determination to review a lot.
