why..?

I got my midterm back from Econ class. I almost failed last time, so I studied more. However, I got the almost same score.・°・(ノД｀)・°・ It's so stressful. If I don't get a B at least in the final, I can't pass that class. I took time to study for this class but it didn't work. I really wondered why.

The professor in that class is a very old man. He doesn't say things directly. He uses NOT a lot in his sentences. I get unsure if he said 'not', so I don't understand what is correct in his statement. In other words, I'm not understanding what he says. And in his class, there is no lecture note or study guide for the exams at all, so it is fatal that I can't understand what he says.

I should have researched about classes I need to take. Since the last quarter, actually since I entered this university, I lost motivation for study, so I didn't really get prepared for anything. I'm often behind in this school. The reasons why I am failing in this class is not only things in the class but fundamental factors in me. ε=(｡・д・｡)
