We’ve had quite a few questions recently from admitted students about the Math 2 subject test. As you read in the admitted student guide that came with your letter of admission, we strongly encourage you to take the Math SAT 2 subject test before orientation. All of the majors at Carolina require a quantitative reasoning course and many of these courses require a math placement score, though there are a few that do not. It's best to have a placement score on file in case the major you choose has specific math requirements.
An AP Calculus score is a fine substitute for the Math 2 test, however we don’t receive those scores until late summer, so you may not be able to register for the math course you want during your CTOPS orientation session.
If you already have an AP Calc score--for instance, if you took the exam junior year--you can use that score for placement at CTOPS. Just be sure to have the official scores sent to UNC-CH. (Keep in mind that you can only get math placement from the AP Calc test with a score of 2 or better.)
If you are unable to take the Math 2 subject test before CTOPS, no need to panic though! Although it may limit your ability to register for a math course during CTOPS, you can always take the test later (or wait for your AP scores in late summer). Depending on when you take the test, you can either register late for a first-semester course, or wait until second semester to take the course that requires a placement score.
Hope this clears up some of the confusion, but please let us know if you have further questions.
