From your other threads it looks like you’re a NYC resident with a 1900 SAT, 29 ACT, a ~96 GPA, and are in the top 10% of your class. If your parents have a $0 FAFSA EFC you’ll get a ~$5k Pell grant and a ~$5k NYS TAP (tuition) grant (that can only be used at NYS colleges). You can take the federal student loan (~$5500/year). That’s ~$15k/year. That’s not enough to pay for a SUNY, but @sybbie719 can tell you if that will cover the cost of a CUNY.
Can you work over the summer? You may be able to raise ~$3k that way. Are you majoring in a STEM field? Students who are in the top 10% of their class and majoring in STEM qualify for a STEM tuition grant. It would replace the TAP, but if it covers full tuition (SUNY tuition is currently ~$8k/year) it’s worth investigating.
Did you apply to any CUNY schools? You need a good financial safety in case you don’t get aid from your other schools. Where else did you apply?
