Should I take Calc1 or CS1 this summer?

I’m currently taking Intro to C so should i go for CS1 in summer? The cons are obviously shorter duration etc and pros are i can give Fe earlier which can help me determine my next steps (in case i fail) and that i will have fresh knowledge of C. Any recommendations? I really want to pass the FE1 first attempt if possible Also what prof woul you guys suggest?
