<p>I was in a similar position with gkc4. I recieved a C each semester starting from sophmore year (after coming off a straight A freshmen year) and my UW gpa regressed each semester due to more and more B’s. Thankfully, while my grades went down, the number of AP/honors classes I took went up so I ended with a gpa disparity of 3.5 UW, 4.1-4.2 W. </p>
<p>Looking back, those C’s probably earned me rejections to schools that I could’ve had a chance at (USC, NYU to name a few) but I doubt they were the primary reason. </p>
<p>In response to the OP, yes, the C and downward trend will impact your college admissions process but the amount of impact should vary greatly. As long as you apply to a diverse group of colleges, it should all work out in the end.</p>
