SLO vs SDSU for Information Systems?

2 years, the cost of living on campus or just near campus is incredibly expensive. I am thinking of just living off campus at SDSU and using the financial aid to cover it hopefully.

If everything is working how I am thinking it should, SDSU tuition is 8,500 give or take and my FA should be around 13,000 ish cal grant and pell grant I could use that left over money to fund me living close to campus and just paying out of pocket for the few thousand. but that is if everything is correct and thats how FA works. this is my first time applying for FAFSA
