I studied the basic level of Korean at the Korean Cultural Center from my country, but I quit after 2 years because they were too strict, to the point I even started failing college because of it o_o. Then I pretty much tried to study at home but it's really hard to be consistent... it's also really hard because sometimes there are some words you use in certain situations that dictionaries or websites don't tell you about, which is why I think it's good to have a professor, but unfortunately there's no other place here to learn Korean :(
