Self-Study vs. Classes

'Sup /lang/.

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

Self-study is great as you can pace yourself however you want. A lot of language classes either go too slow or too fast. Classes are essential.

Also, I don't believe anyone can learn Chinese in 1 a year by themself, unless they hole themselves up in a room for a year and devote all their time to it (oh and you're Einstein). And even then, you'll fucking have no clue how to pronounce half the shit – there's all that tone/pitch stuff you've gotta figure out. Not to mention Chinese has no standard written form.
