Are you a Texas resident? Isn’t there a state grant in addition to Pell Grant? Also you can borrow $7,500 the last two years.
You might need to share an apartment with roommates close to an instate public college or commute from home.
How about Texas A&M? I thought they had the Aggie Assurance where low income students can get free tuition, then Pell and loan could pay for housing and food and books.
