I'm a mix of happy and mad right now. Both are because of school. Which should I tell you first? Good news or bad news?

I guess I'll say the bad news first, so that I can hopefully end on a happy note. Well the bad news is this:
I blew up at a teacher...again. It happened because my religion class was shown our marks. My friend and I went through the breakdown of everything we did and at the end of the mark entries, I noticed that everyone in the class got 70% on two of the entries. At first I was confused, then I remembered that my teacher had said that he "had too many marks" for us, so he was giving us credit for one assignment by simply going with the grading curve. I had assumed that he meant that he would follow our individual averages, not grade the whole class as one. I was extremely peeved at his actions, when I found out I was mistaken. I had a 91 average, and you would think getting two 70s would completely throw off my average, right? So did I, so I began to question my teacher's choices on the marks. He replied that it wouldn't affect my mark at all, or if it did, it would only be half a percent lower. So I basically shouted at him that half a percent is still lowering my mark. Then he had the gall to tell me that he has the authority to boost up my mark by two percent. First of all, that had nothing to do with what I was saying, and second of all, whatever happened to "your mark is exactly what you give me"? Teachers are always saying that they don't give students marks; students give themselves marks. So how come my religion teacher can so calmly say that he has the authority to change my mark at his will? That's just abuse of power and unfair to students.
Basically, after that, he pretty much just told me to shut up, and I was told by my friends that my face was really red, and then I just started crying from the unfairness of it all. The guy who sits next to me was really nice about it and he kinda tried to make a joke out of it all. I laughed and then the teacher began a new lesson, so I tried to put it out of my mind. But it's the second time a teacher has adjusted my marks to suit his whim, without a real reason. I'm still mad about the first time. This time I'm absolutely furious.

Anyways, on to the good news. My school has an award ceremony in the next two weeks. I've received five awards: one overall achievement award, and four subject awards. I can't wait for awards night to see which subjects I received them in.

I'm done for now, because I'm going to go research whether or not teachers can legally take away marks like that. If you know anything, don't hesitate to comment.
