The schedule is okay but that's ONLY assuming you have class, not friends to hang out with, classes to study for, college soon if you're not in it already and then the bird will be left alone for longer when you have to be away studying, out partying, etc. etc.
I never recommend these types of parrots for students. Your life is just beginning to grow and your schedule will begin to change a lot, with social life, school, work (because that's what we all go to school for), traveling, etc. it will be a better choice to wait until you are at least 21/out of school/making your own money and live somewhere permanent before you consider caring for a parrot.
