SHOULD I CHANGE OR NOT?

During this days I can't stop thinking about that. It is become like a real obsession for me I think.
I know that the school started more than two month ago but I don't actually care.
I'm going to explain my frustration:
I have Health Occupation class the last two hour of my schedule. In this class we are supposed to study the human body and prepared ourself to be a doctor or a nurse. I thought at the first time that this will be one of the best class I've never had but I was really wrong. The only thing we do is fill stupid paper and worksheet without learning anything. For the first two month we've talked about stuff like ethical, legal duty, leadership, professionalism and boring stuff like that. And we decorated a jar to raise money for a cancer alliance. Every Friday we have a meeting with the class to talk about thing that I think are stupid and in which I'm not really interested in like bake sale, HOSA meeting (HOSA means Health Occupation student of America and everyone who has this class is a member of this foundation). I'm feeling as I'm not learning nothing in that class and as if I'm wasting my time (is two hour class, which is a lot of time if you consider that your schedule it's just formed by six classes) and as if I'm losing some opportunities to take classes more interesting for me. But there are some problems: this is a special class and is in another building near my school, my schoolmates are from different school near Escanaba (there are only other two people in my class who came from my same school, the others are in another class) and my teacher literally loves me. She hug me everyday and introduce me as the brilliant exchange student from Italy to everybody. She said i'm her favorite student and that she will be my bridesmaid at my wedding. But, anyway, I went to talk to the officer who makes the student schedule and she gave me a paper to know what classes can I take. I'd like to take some AP classes and one of them is AP biology. I went to talk with the biology teacher but she told me that her class he's already full and there's another guys who need to take this class for graduation and so there won't be enough space for me. The only class I can take without completely change my schedule will be something like art or chorus and maybe AP chemistry; but I already have chemistry on my schedule on the fourth house and also if we're doing things that I've already studied I don't think they we allow me to take two chemistry class. The other option I'll be French but the are only sophomore and freshman in that class... and I'm a senior. Maybe I can join the band for an hour but I can't play any instrument, I will really like do that only if they will teach me to play an instrument. Everything will be better than stay in a class for two hour without learning anything. But it seems like everything is impossible to do. And, last but not least, they won't allow me to change my classes before the end of the semester, which is in January. So I don't really know what to do: I don't want be in health Occupation class for another day but I can't change class before three month. And on February we are supposed to do clinics and go to the hospital to learn how to do basic thing: i don't really think it's gonna be as great as it looks like. I wish I was able to change my own class from the starts when I went to school on the first time. But the truth is that another person make my schedule and I just say that it was ok without asking for anything better. I'm so upset for that in this period and I can't stop thinking about which classes I would have take instead of the one I have now.
I already change some classes. The second day of school I switch conservation with chemistry accelerated, and few weeks ago I change CPI to take a math class (pre calc). So now I'm ok with my class (also if chemistry is too easy). I just want to take an AP class, give up Health Occupation and take another stupid class as art or chorus. I'm so afraid that change all my classes in January will be a mistake. I hope to find a solution for that as soon as possible.
