Background
How to study Korean. Hmm... I'm interested in learning Korean... I know how to read it... Maybe I'll click on that...
99.9999% of Korean grammar and 9000+ Korean words?! Whoah! That sounds way too good to be trustworthy and real. I am a devout completionist learner when it comes to languages, I learn every single word and grammar point until there is no more.
Question
Will How to Study Korean really make me a Korean-speaking master?
Will I need to supplement it with other things, or can the website do what it claims it does, and make you require nothing else. I don't believe it, because I think that listening practice, conversation practice and other real-life kinds of practices are really important in language learning, as I don't want to sound like a textbook.
Is it possible to learn Korean using only How to Study Korean?
Of course, I personally am not only going to use that site because I don't want to sound like a textbook. I'll supplement my learning with listening practice, a few native speakers, practice every day, conversational practice, etc.
But what are the answers to the above two questions?
