Yes, BA does have grammar courses, too! I'm probably going to pick one up in a couple of months. Right now I'm focusing on the basics. I don't think I mentioned it here, but for some reason I tested beginner level 2B when I took the Sejong Institute test. But that only tests for grammar/vocab and listening ability. I haven't had a lot of speaking or writing practice, so right now I'm focusing on learning to express myself in simple sentences.
