To each his own. Because of the nature of this board you will get opinion from DC's that are now studying to become MD's. I myself wanted more than Chiropractic could offer so I went to medical school. I enjoyed Chiro school and if I didn't have to work so hard to sell it I may not have moved on to the additional 7 years for med school/residency. After finishing med school I can say I am loving it. I will get to work in an ER seeing patients who's conditions I can fix/change/manage and see results in a short period of time (not the three time a week for three months results). I still enjoy chiropractic and will still on occasion "palpate"

family and friends.
As for the OP's question the minimum is 2.5 and if you have it and can finance your education I would say you're in.
