It's useful to get the degree even if you think you won't need it, esp. since you're so close to finishing. Ten to fifteen years later, you might decide to go to medical school, or to law school to become a human-rights lawyer, or to get a master's degree in astronomy. It'd be a much bigger hassle to have to go back and finish the B.S. at that point.
If you are an autodidact with drive on something you love, and want that to be your career, and don't think the loans justify the lack of payoff. If you are born wealthy, there's no point in college other than using it as an act of rebellion to piss off your Grandfather and get an Art degree. If you are disadvantaged and of color, it might be your ticket to acceptance in a totally fucked society (USA).
Otherwise, go to school, get the cred, then get the actual knowledge by learning on the job and from the graybeards. That also starts your network, which is infinitely more important than credits and a piece of paper.
IMHO (colored and completely biased by my non-neurotypical brain and what it has had to endure), college/Uni degrees only assert that you can slog through BS day after day. They are the perfect bona fides if you want to be part of the machine.
This, naturally, excludes anyone seeking a Physics degree at CCNY and similar. For anything other than the top 1% of actual Comp. Scientists in Academia (and thusly Google), the thing you should remember is that in 5-7y no one will give 2 f*ks about your degree unless they are an alum.
Many schools allow you to finish by taking classes online. See if you can take a single class online at a time for the next few years.
Either way, your grades don't matter now, so just do the bare minimum to get the degree (now or someday in the future).
Fair or not, having no college degree can cause people to dismiss you.
