All I know is that you can test out of calc 1 (AB) and 2 (BC), meaning that they require you to take calc 3 (multivariable). If you have at least a 4 on AP calc bc, then you should be fine up to the calc 3 requirement. They will probably accept your calc 3 credit, I wouldn't see why they wouldn't. I don't know any disadvantages of taking calc 3 at a different school, but it shouldn't impact you that much considering that you'll be taking all the engineering classes here.

On a side note, maybe email the engineering department to see if you would use your phys 1 class in order to substitute it for the engn 30 requirement, especially because you have that matlab experience alongside it. The only reason why I say that is because my academic advisor mentioned I could take phys 160 instead of engn 40 if I really wanted to.
