Should I take the AP test after a CIS Course?

<p>I will be a junior next year and am currently planning on taking CIS Intro to Physics class (offered through my school - the curriculum is exactly the same as taught by the University of Minnesota). My teacher told us that we will be learning more than enough to take the Physics B, if the not the Physics C AP test. I was wondering if this is worth the trouble to do so if it is already a college course to begin with.</p>
