Is Calculus 1 required/strongly recommended to take Calc 2?

The title sums up the question. Thanks in advance for replies.

Yes.

Spanish 2 builds upon what was learned in Spanish 1. It’s the same with calculus, so yes.

Yes. Usually, Cal 1 is differential calculus and Cal 2 is integral calculus. Integral Calculus is built on the Differential Calculus.

@4kidsdad Ok, thanks. I wasn’t sure if it was something like AB and BC

This is an oversimplification, but:
AB = Calc 1
BC = Calc 1+2
