Some code schools are free (and take a cut from your future earnings). But there's differing opinions on whether they'll really lead to fast and gainful employment.

If your long-term goal is a degree/career in biology or neuroscience, there's another option. Maybe you could try to get a job in a biotech firm. (Any job; just to get your foot in the door and make some contacts and get to know a bit more about the field.)

And of course, you can always just take an unrelated job, and then start taking classes at a good (and low-cost) community college. It could even be a part-time job. You can transfer those credits to any four-year college later if you end up with more college money down the road.

I'm not trying to talk you out of code bootcamp. But you do have a lot of options.
