When I went to school, I didn't want to do what anyone told me. In my Senior year, I only had an art class, so he would say what the assignment was and like any art teacher they would give you an example of what to do. So then everyone would do the example, but I would take something that I had been working on and I add more to it and relate it to what we were doing, and even if it was completely and utterly not the assignment, I would say it was and I would explain why (metephorical explanations always work). The point is, since you are the artist, no one can contradict you. Being the artist of a painting, drawing, photograph, computer art, what ever, means that you are now GOD. And then after I showcased my work I would go to the teacher and say grade it now, cuz I am not turning it in, and that's what my senior year consisted of.
Now that I am in college (yeah, it's a little bit different) But I refuse to do what anyone says because it inhibits my creativity. I take it you're in a Community College right now or maybe its a summer program whichever, which not very different from hs. I don't know what your computer class entails, but if you can find anything that my story applies to try it.
