Are you in Hutton? If so, definitely take C106 and K204 freshman year, as the honors versions of these classes are very easy to do well in. I would also take K201 or K204 first semester so you can take K303 second semester. K303 is the easiest I-Core prereq in my opinion.
You will need to take all classes from this list before junior year, so mostly fill your schedule with them: http://bulletins.iu.edu/iub/kelley-ugrad/2013-2014/program-details/course-degree-req/i-core-prereq.shtml
In addition, find a couple of gen ed classes that double count for WC and A&H credit, and one that counts for natural science. http://bulletins.iu.edu/iub/general-education/2016-2017/requirements/index.shtml
I would take 1 class each semester that double counts, and one natural science class whichever semester it fit better.
Use ratemyprofessors.com and http://gradedistribution.registrar.indiana.edu/ to help choose classes as well. It’s usually easier if you post a schedule on here and request feedback rather than having other people make one for you because only you know your interests/strengths/weaknesses. You should have all the tools now and I’d be happy to give you feedback on a sample schedule or answer any questions.
