Kelley Transfer from Ivy Tech

Currently, I am an Ivy Tech student with a 3.67 GPA. Currently, I have all A’s in my classes, with the exception of Calculus, which I have a C in. I have heard (IUPUI) Kelley will not let those with a B- in a class into their program, so I am currently at the cross roads. Should I withdraw from Calculus and retake the class over the summer? Should I just stick it out and pull off a C, then retake the class over the summer? What I’m unsure of is whether or not to a withdraw would look worse than a C/a retake. It is frustrating because I have never received less than a B in my time at Ivy Tech, I’ve made the Dean’s List every semester, but messed up my midterm exam and it looks like it could potentially mess up my future. If anyone has advice, all ears are open! It looks like I will graduate with either a 3.5 or a 3.6 cumulative GPA, given this semester I have all A’s (which count as a 4.0 on Ivy’s grading scale), the calculus class has just given me some trouble.
