You should study the requirements for standard admission to Kelley rather than being spooked by an advisor’s advice, unless the advisor can give you good reasons for taking their advice.
The main direct admit list of classes is very clear cut:
Completion of at least 12 credit hours from the following courses on the IU Bloomington campus:
BUS-K 201 or BUS-K 303
Choose one additional option from this list: ENG-W 131*, BUS-C 104, BUS-C 204, BUS-L 201, or BUS-G202 AND BUS-D270
Choose two additional options from this list: BUS-A 201, BUS-A 202, ECON-E 201, ECON-E 202, MATH-M 118*, MATH-M 119*, ECON-E 370*, OR BUS-A 100 AND BUS-G 202
The entire list of requirements is here:

Classes that many students take before getting to IUB from the above list include W131 and E201, which can be tough grading at IUB. Also, having credit for E201 allows you to take Bus-G202 at IUB instead of a more difficult three-credit class. You need 12 credits taken at IUB in the correct groups. Some of the other classes, like W131 and E201 can be taken at community college and transfered to IUB. Check the credit transfer list to see what will transfer from which colleges.

Like Hkem, I recommend the path of least resistance as far as which classes to take at IUB is concerned. Easier classes usually leads to better grades.
