....here where I live in Michigan, there have been many people doing just what Chris mentioned. However, when Michigan and Michigan State realized that it was cutting into their enrollment potential, they changed their curriculum requirements such that the kids who thought they would save 2 year's tuition money by going to JC found after the fact that these schools no longer accepted the transfer of some of the credits - particularly some of the ones that went to core major requirements. This resulted them in having to pay for another semester's tuition anyways. ( I also am friends with a Junior College career counselor who had to deal with this issue).
The solution is simply to ensure from both sides (JC and future desired school) that they do indeed accept the credits.
