Keep playing, it's about being seen. Some bands are just seen right off the bat (Smashing Pumpkins), some bands slug it out for years (Everclear, Goo Goo Dolls). You need to stay in school for every reason that common sense can tell you. What school is also really good for is a built in network to get people to shows. The best way to get people to shows is word of mouth of a common social group- with school it shoves everyone together, and it's a lot easier to let people know when and where you're playing. To quote Schwinn: "You've got a lot of years ahead, enjoy the ride." PS. Don't cover the theme song to the TV show "Makin' It" by the guy from the Dr. Pepper commercials and "American Werewolf In London." Bad song, bad show.
