<p>The community college I'm planning to sign up for has fall, summer, winter, and spring classes, so that means it's based on the Quarter system, correct? </p>
<p>In order to transfer to a UC, I need 90 quarter units. Each class is probably worth 3-5 credits. So I need to take how many classes each quarter in order to transfer within 1.5 years? </p>
<p>EDIT: If I got 3 on my AP Biology exam from high school, does it count towards the 90 quarter units?</p>
