I'm convinced that a classroom is the worst possible environment for actually learning a 2nd language. There are just so many reasons why.
Probably the most insurmountable one is that the pace at which the class can move is limited by the pace at which the least motivated student is going to learn.
But I also think that it's just a structurally bad environment for efficient language learning. Since everyone needs a chance to participate, you spend the vast majority of your time listening to other people who don't know the language any better than you do, so there's just not much to learn from them. Since you're working from a textbook, everyone has to read the same uncompelling least-common denominator materials, which, by virtue of being boring, are just as likely to sap as to sustain your motivation - and an unmotivated mind isn't going to absorb much.
I'm starting to feel that way about canned programs in general. I've been working on the kanji lately. At the start, a friend of mine told me he thought I was crazy to do all my own flashcards (though I am following the learning order from Remembering the Kanji) when I could just subscribe to WaniKani and have it all handed to me on a silver platter. A couple months later, he estimated I had learned more kanji over 2 months than he had in years. Just assembling your own materials admittedly involves a lot more up-front work and a steeper learning curve, but the process itself has a lot of mnemonic power.
