Class transfer question

<p>This summer I overloaded and took calc 3 and physics 1 and got a B in physics and a C in calc 3. My first C, anyways im a DGS student sophmore transfer and want to transfer to chem E.
Do you guys think I should retake calc 3 in the fall at u of I for a better grade or is 1 C not gonna hurt me? Also, my gpa is pretty bad like a 3.1 something since I pretty much got all B's and 2 A's.
Now I will try to get a high GPA this fall, like a 3.5+ Atm taking physics 212, chm 222 lecture only, chbe 221, and 2 gen ed classes.</p>
