How does this ap credit work

<p>OK. So I want to use my AP credit for CALCULUS AB and MACROECONOMICS for satisfying parts of the math and social/behavioral science IGETC areas. Is there any limit to how many of these units (obtained from AP credit) that can be used towards satisfying areas of IGETC? These courses have no affect on my college GPA and only add to my total cumulative units right? </p>

<p>For calculating GPA, I only use the units from courses I took at community college and received letter grades for?</p>
