This depends on a lot of things: How much debt will you be in at the end? If you press on now, will you actually finish? Do you have the personality to make money without a diploma?

I made the mistake of pressing on early and incurring extra debt, but not pushing through to get a diploma.

Not having a diploma is hard if you want the kinds of jobs that often require one arbitrarily. Doing something freelance or taking a non-degree job are hard in other ways. Fortunately you can test this with some time away from college.

There's also a difference between what you CAN learn on your own and what you will actually take the time to learn. I know there are things that I would have been forced to learn which I have neglected to.

If you're probably not going to finish, then cut your losses now, but make a clean break that will make it easy to go back. Finish the semester well.
