My D took some duel credit classes in HS, IU only took two of them and gave her 6 credit hours but they did not count towards her IU GPA. The only thing that counted for her were the 2 ACP classes she took which were IU classes. So with the two transfers they took, the 2 ACP’s and the 1 AP score she already has 15 credit hours on her IU transcript but of those hours only her 2 ACP count towards her GPA so starting with a 3.65 based on those two.
There is a place on the IU website where you can check the credit transfers to see if they will take them. You would put in the CC you took the classes at, then the name of the class and it will show you what IU class it would map to. You could start there to check on if the classes would even transfer to IU.
