Should I transfer AP Calculus BC credit or retake MATH 1551 & 1552?

Hello,
I got a 4 on the AP Calc BC exam and it covers both Math 1551 and 1552. Even though I got that score, tbh I felt shaky during that class and it was really hard for me. A faculty from Tech said it is better to “move on” if students have credits, but I am not sure if it truly is better to move on to take MATH 1553 and 2551 (required courses) when I wasn’t even that confident in the AP class. Does anybody have advice or can share their experiences skipping or not skipping? Thank you!
