Finish that four year degree! You can never be over educated. As a number of individuals in this thread have stated it’s in your best interest. God forbid, one day you don’t make it through your medical, you have a bad day during your flight check, or the airline goes bust. What are you going to do then? Hedge your bet with a degree in another field other than aviation. Don’t be afraid to diversify your career aims. Trust me you won’t regret it.
