Taking AP Calculus AB with a B in Pre Calc?

Hi
So, right now I’m in a bit of a dilemma. Last year, I took Pre-Calculus Honors and passed the class with an 86 (got a D on the final). However, this year, I am set to take AP Calculus AB, but I feel like I’m not ready for it. My question is: Should I take AP Calculus AB even though I got a B in Pre Calc Honors?
Thank you!!
