The problem is…none of these suggestions will get you to $15k a year, which is what Rutgers would be for room and board only. My guess is most will still be north of $30k.
You say “financial aid” but do you qualify? Living in NJ with at least one parent employed by Rutgers, lead me to believe you won’t have an especially EFC. You may be relying on merit and that will be tough to meet Rutgers with free tuition- not too mention being better academically.
