Narrative:

Practicing autopilot loading procedures IFR approaches (not logging and not under the hood) single pilot. Flying back to home airport two flight school planes in pattern. They seemed to be fighting with each other. I called 8 mile final 5 mile final and then had one aircraft cut me off by turning base. I called my position at 3 miles (two miles away from aircraft) and asked where he was. He realized his mistake and just did a low approach. He was never a factor for conflict; but was still not a very standard way to handle the situation; by just calling base and not verifying my position; as I was a full stop. Other aircraft immediately extended his downwind for me. With their comments on radio and nonstandard patterns made tough to concentrate on my altitude and localizer so; I did a visual approach to airport (hand flown) from eight miles out. Standard communication and better coordination between rival schools would help traffic flow for everyone. Should not have been an issue with just three total aircraft. Not a safety issue today; but if one of the aircraft would have been a solo student; I am sure they would have been very confused. Better coordination/professionalism would allow all aircraft to accomplish their training goals.
