Self-Study vs. Classes

'Sup /lang/.

Which is better when learning a foreign language? Self-Study or classes? Which do you prefer?

You can't fucking learn a language from classes, they're too slow and you'll forget too much shit by the time you would get fluent from all that studying.

Self-study is far more effective. There's definitely some flaws in it, and it requires godly discipline which most people these days don't have, but other than that, it's vastly superior.
