What kids of professional development do you do to keep you "edge" as excellent students?

I think that what keeps me an "edge" excellent student is really simple, what I do is doing my homework once I get home; reading books also helps me. I also study the day before any exam. I think that just by doing those things, it makes me a good student. Also, I have good behavior in class, and to be responsible. That’s what I do or try to do to be an excellent student we have to be responsible.
