I am quite surprised they allow you to pass out of calc II from just the AB test. The calc II curriculum at your school is probably less in depth than the equivalent at my school (description of calc II: Techniques of integration, first order ordinary differential equations, conic sections, polar coordinates, vectors, two and three dimensional analytic geometry, infinite series).

I have never heard of anybody who has been glad to retake a class they got AP credit for, but have talked to many who have regretted retaking a class.

I would say skip the class and go to calc III.
