<p>Cardinal Fang, it’s not that hard, you don’t learn a year’s worth of material. You don’t get college credit. You take calculus again in college, but it will be easier, because you’ve seen the first __ months of material. Many parents here recommend retaking calculus even if you’ve taken AP Calc. (I’m not one of them though it may be that some kids may want to retake calc in college* if * the college course covers more material than AP Calc, or they feel their understanding is shaky, or they do poorly on a college’s own placement exam.)</p>
