Would I be cooked for Math 20C 🙏

Hi! I'm an incoming freshman majoring in CBN.

I took Calculus BC when I was a high school junior and I got a 5 on the exam and an A in the class. Since it's been over a year, I feel like I've forgotten a majority of the Calculus BC specific content though (so basically I forgot the majority of Math 20B). Everything in Calc AB I'm pretty sure I remember well. I was wondering if I should retake MATH 20B since it's been such a long time, or if I should just wing it and take MATH 20C?
