You can look up grade distribution for all classes at IU here: http://gradedistribution.registrar.indiana.edu/
Here are the standard admit requirements: https://kelley.iu.edu/Ugrad/Admissions/CurrentIU/page39067.html
C104 and C204 are extremely easy to get above a B in, so I would recommend taking C104 first semester and C204 second semester. C104 is business presentations, and C204 is business communication, but is mostly focused on writing. You don’t have to be great at public speaking or writing to do well, you just have to put in some effort.
K201 is required to be a standard admit, and K303 is very easy to get a B in, so I would recommend K201 in the fall and K303 in the spring. These are Microsoft Excel classes.
Many students who aren’t good at math struggle with M118 and M119 at IU. If you aren’t good at math, you might want to take those at a CC. If you aren’t going to take the math classes at IU, you should probably take E201, and A100 and G202 for the “two additional options from this list”. E201 is a prereq for G202. If you do well in A100, you could replace G202 with either A201 or A202. Compass (T175) is an easy A and required. I would plan on something like what I have below. Note that you need 30 credits to apply to Kelley. If you live in the KLLC, there is a required 1 credit class each semester that would get you to 30. If not, you could add a 1 credit activity class each semester like basketball or tennis.
Fall:
C104 (3 credits), K201 (3), E201 (3), A100 (1), T175 (1.5), Gen ed (3)
Total: 14.5 credits
Spring:
C204 (3), K303 (3), G202 (2), Gen ed (3), Gen ed (3)
Total: 14 credits
Gen ed requirements can be found here: http://gened.indiana.edu/Students/requirements.html
You need 1 natural science (not all N&M are natural science), 2 A&H, and some combination of classes to fulfill the world culture requirement. Let me know if you have any questions.
