Its way to risky to go full time in the bitcoin because there are too many risks if you ask me.
school purposes and real life purposes are different things, school expenses are not too much, but when it comes to your real life, you simply cannot depend on bitcoins, what will you do if bitcoin pay you in peanuts in future?
Yes, you cannot compare school expense to life expense. Say that again when you are paying for electricity, water and house mortgages or when you quit school and rely your future in bitcoin. For me, bitcoin is really good extra income but I cannot still rely my life expense on it. I am not that big earner yet, maybe someday when I become really really good in trading, maybe I can think of quitting my day job.
