That sounds like a good plan to me. You should be fine in IU accounting classes if you have prior experience. Just go to class and do the practices tests and you’ll be fine. G202 and C104 are very easy to get a B in, and you can actually look at previous grades here: http://gradedistribution.registrar.indiana.edu/
I would add Compass (BUS-T 175) and a bunch of gen ed classes to fill out your schedule. The requirements can be found below. You basically need 1 natural science class, 2 arts and humanities, and 2 world culture classes, and W131 if you can’t get credit for it. There are some classes that double count for arts and humanities and world culture credit.

Everything else should be filled with required Kelley classes. You can also see a list of gen ed classes in that link. I would find a few that sound interesting and have a decent grade distribution. I took Ancient Greek Culture (CLAS-C 101) and Intro to the Old Testament (REL-A 210) and they were both decently easy classes that double count. Let me know if you have any questions.
