I understand ISAs work for tuition, but what about regular bills?

This is one of the big unsolved problems with Bootcamps right now. The program is a fixed length and people work really hard to get their finances in order to finish the bootcamp. They look at CIRR results and feel like there is a 90% chance of getting a job within six months, and then they cross their fingers and go for it. It can get extremely stressful for people. Lambda School (now Bloomtech) did an experiment with cost of living stipends that get paid back afterwards. Loans are another way. It gets a little messy if you have a job guarantee on the tuition but not on the cost of living loan. From what I've seen for people I've worked with who didn't have jobs, people have lived with family, relied on their partner's income, worked gig economy jobs. I would try to find ways of adding to your savings even if you get a loan to cover cost of living. Especially in the job market right now, things change week to week, adding even more to the stress.
