Is your son Trinity? If so, he is limited to using 2 to graduate though others can be used for placement. Also, the two used will be electives and will not count towards the Areas of Knowledge or Modes of Inquiry (see
T-Reqs). As for if it is a good idea - depends on how good the AP class actually was
If he's Pratt, it's a whole new world - almost all APs count except:
- Stats does not count
- Only two of the fice Social Science / Humanities classes can be AP
- At least one semester of Physics must be taken at Duke
