You’re posting mixed signals. Your parents are refusing to pay, so why would you count on them to co-sign loans all for 4 years? You run the risk of having $20k+ in loans and then suddenly your parents can’t/won’t borrow more…then you couldn’t afford ANY school to complete your degree.
Take the full ride for at least 2 years. Let your parents work on their situation. Then apply to transfer and see if you get the needed aid. BUT…do not cut ties with your current school until you have a KNOWN affordable school to transfer to.
But, start at UIC
