<p>I've taken the APUSH and AP stats and will take the BC CALC, AP LIT, AP SPAN LANG, and AP PHYS B tests and I hope I'll get a three or higher on those last four. But I'll be majoring in Computer Science at the University of Toronto or UMass Amherst's Honors college. I hear that a lot of people don't use their ap credit so they can repeat classes and get better grades. I'm not immensely smart, should I just repeat the classes or what?</p>
<p>I've heard that some people get to skip a year and graduate in three with AP courses. What would be the pros and cons to not using my ap credit?</p>
