Should I drop out of college?

I have a midterm exam in 2 hours that I did not study for and my teacher said that If I didn't p this, then it would have a great effect on my grade for the quarter. I have the option of going to school and failing the test or to drop out and get back in to school until next quarter. And this is also the only cl I'm taking. I didn't study because I work in full time to pay for bills and if I don't work then I'm out on the streets. What should I do?!?!?!?!
