I need job advice

Recently with some changes in management, my work schedule has started to overlap with my classes. I've talked to my boss and he says that this is supposed to be a new normal schedule and that the changes are permanent.

I want to know what my next option should be, I'm already taking my last few classes this semester so quitting now would be a literal waste of money, buy at the same time I need this job to pay for gas and transportation.

Can anyone help me in this predicament or point me in the right direction for some help?
