GI Bil For The Airforce Reserves, Please Help!?

Iv been really wanting to join the Airforce reserves to serve my country. But i haven't decided on how long i want to enlist for. I want to start out with a 2 year term and see where it takes me, but I am really concerned if the GI Bill will help pay for my education. I tried to look it up yesterday and i read somewhere that you have to start with a 6 year term in order for them to pay/help pay for college. But idk it doesn't sound right to me, i thought if you were in any branch of the armed forces for any term (2 years +) and serve your country you have the opportunity to have money for education. Please help!
