Your first step needs to be a sit-down with the financial aid folks at your current school. Not a work-study student who answers the phones, an actual financial aid officer. Together you can map out your path to getting a degree and ascertain whether it’s feasible at GW or not. There may be resources you don’t know about. A college where you are enrolled has a greater incentive to help you tap those resources vs. a college which has not accepted you yet.
How are you “covering” your tuition now?
