Thanks for the examples, I know what you mean. We recently went back over たら、と、ば、なら in class. Our teacher didn't really give us concrete instructions on when to use what because he felt that since language is fluid, you just have to hear it enough times "in context" to be able to eventually discern if something sounds "right" or "wrong."
I have some grammar books, but the meaning for very hard (for english speaker) grammar points such as those is still really hard for me to understand. Another one is transitive vs intransitive verbs. Basic examples like 窓を閉める vs 窓が閉まる。 (hope i did that right) are pretty easy for me to get. But when you put it a complicated context / use harder verbs or situations, it's really frustrating.
I guess the point I'm getting at is starring at a grammar book and its example sentences hasn't really been cutting it for me. I understand the grammar point to some extent, but if theres 5, 10 or even 15 example sentences, I still won't understand the grammar point in a lot of situations that are not exactly the same as those examples that I memorized. Is this where material like manga comes into play?
I feel as if I have ZERO knowledge of slang or colloquial terminology / usage, but I have a pretty basic understanding of a LOT of the grammar that is used in day to day conversations. At this point, I wonder if just reading, listening, and talking through as much material as possible is the best course of action; rather than re-reading the same old grammar rules, example sentences, textbooks, etc...
I really appreciate everyone's input. I'm really new to trying to use sources other than the given textbook to learn Japanese, and I'm just getting frustrated with my lack of progress and difficulty of the course load
