<p>I don’t know all the ins and outs of Chicago’s AP policies, but the answer to your “most urgent question” is pretty simple: neither Chicago, nor any other elite university, is going to care about what you get on those four AP exams. Furthermore, unless you really want to graduate in three years or less, you may not care about any of your AP exams. Most students aren’t so excited to give up a huge chunk of their ability to take electives at the University of Chicago.</p>
<p>As for Latin and math, they have placement tests for those. I think everyone takes the math placement test regardless. A good score on the Calculus BC exam would probably guarantee you the opportunity to take honors Calculus, but so would a mediocre score, and if you want to take honors Analysis you will have to prove it on the placement test. The situation with Latin is similar – you can place into intermediate Latin, but you may be able to do better by taking the test.</p>
<p>I wasn’t aware that AP classes could substitute for the science requirements of the Core. Others can address that.</p>
