Elementary Calculus I (Comp Sci)

I'm a university transfer student beginning his first year in CS. I've taken Cal I in the past (fall 2014) and attained a C+. Carleton awarded me transfer credit.

I can't help but wonder if I'll be at a loss by not having it fresh in my memory and having a better understanding this time around. Should I consider retaking the course during my first semester or take that transfer credit and never look back?
