No. The first two years of the program are designed to be a trial period for you. The classes during this time provide general information about the Air Force. It is a time to decide if ROTC and the Air Force are for you without commitment. For instance, if you enter the program with a 4-year scholarship, you can quit after the first year with no obligation. If you are awarded a 3-year scholarship coming into the program, you aren't committed until you accept the scholarship. If you don't accept the scholarship, there is no commitment until a contract is signed.
