Is 16 credits too much for a freshman schedule?

I currently have 13 credits in my schedule, and I want to add an elective course (CGS 2032 3 credits) into my schedule simply because I’m interested in the course itself. I’m wondering if this would make my schedule too packed…

The courses I have now are:

ENC 1102 Arguments and Persuasion
MAC 2312 Calc 2
COP 3503 Prog Fundamentals 2
LIN 3010 Intro to Linguistics

Would adding another 3 credits be too much? And does anyone have experience with CGS 2032?

Thanks in advance!
