Why do you want to get good grades? answer whatever that comes to your mind?

Kids work for good grades because their guardians have prepared them for that purpose. One thing that almost everybody forgets is that the school is supposed to teach the kids how to do well, not just demand it. The situation has degraded to the point that college professors tell their students not to bother them because they didn't get their jobs by being good teachers. And then the student is treated like a criminal if he is unable to learn by his own efforts what he needs to know. In most universities there is an army of freelance tutors who teach the students enough to pass their exams, because the school does not.

And then comes the ultimate ripoff: after all those years and all those loans, there are no jobs.

Get a simple job and a cheap pad within walking distance. That is so you don't have to waste your money on transportation. Save half of everything you earn. Yes, half. To start, keep your savings in gold or silver coins which you do not store in anybody else's vault. (IOW hide them at home.) Spend your evenings studying investment books at the public library. When you are smart enough then you can make other investments. If you earn ten bux an hour and save half, in only ten years you will have A HUNDRED THOUSAND BUX not counting interest or capital gains or paper profits: only principle. There is no other plan that will give you a net worth above zero in only ten years. And there is no school that will teach you any such thing.

Does this plan work? Andrew Carnegie worked five years, saved his wages, and then put it all into a tech stock: telegraph. You might have heard the name. His hobby was building concert halls and libraries.

So you can have bragging rights and show off how smart you are.
