<p>Dude, you should just cash in on the AP credit if you plan to take 1501 and 1502 (seriously, it “can” be nice to take some classes at the college level that you have credit for, but those are not necessarily among them. Perhaps take their b-schools version of stats. For example, the one at Emory is far better than AP or a regular stats. class in terms of showing you relevant situations in which statistical analysis is useful. I’m sure Tech should have a decision analytics course as well). The course can be very challenging depending on who you take it with. And when it comes to traditionally difficult instructors or courses at a college, it’s not often the material (though sometimes it is. Like at Tech, they may emphasize or cover theorems that are not typically covered in AP or IB) that makes it different from high school intensity so much as the types of exam problem types they give. For example, a difficult college math instructor may be more into writing proofs and deriving things based on the main theorems, whereas AP can be challenging but is more plug and chug/algorithmic type of situations where you get it if you just know the main point of the theory at work. They aren’t asking you where the theory comes from and to show it. Also, some may put some of the more challenging concepts in the context of an applied or word problem which may throw some people for a loop, especially if it isn’t the traditional related rate or optimization types. Also, calc. 2 there typically has a fairly intense linear algebra component as opposed to just sticking to integrals, series, and sequences (they move through that pretty quickly). </p>
