The content is poor. I'm evaluating after listening to half of it. You don't need to listen to it all. I think it would be good for those who don't want to study from books but have money to spare. It's called beginner level, but this is... disassembly, assembly, disassembly... There are more than one or two instances where they say things like this. It's even more confusing. This isn't a lecture worth listening to for 140,000 won. I don't feel like they've done any proper analysis. If you're not going to cover a lot of content because it's beginner level, lower the price. If you're going to use beginner level as an excuse to say you can't do this or that.
