Beautiful inside my Mind

It just irritates me that my japanese teacher keeps going on how we're probably not going to get an A for japanese and we should try hard for our other subjects etc. I feel she's never really tried to seriously help us, like telling me how I can improve. I didn't come to class to feel demoralized! And I feel our lessons are totally ineffective. What to do? Well if she's not going to help me I just have to try to help myself.
