After I graduate from AISOM, is it mandatory that I enroll in ACU upon completion of AISOM?
No, AISOM is a total stand-alone program. You do not have to go any further unless you desire a degree. ACU is simply available to you as ACU guarantees AISOM course transfer acceptance. You are under no obligation to study beyond the AISOM courses. When you graduate from AISOM and you have paid all your fees, you can transfer your credits to ACU or another school of your choice.
