Departments have different criteria for whether to accept AP courses toward the major. General equivalences for international placement exams (such as IB) can be found here: https://trinity.duke.edu/undergraduate/academic-policies/credit-AP-IPC-PMC#IPC. If you have questions about specific exams, please contact the relevant department here at Duke.

* A few notes:  Some courses (for example Biology 201L, Econ 201D, Math 202, 212, 221 and Physics) have additional pre-requisites that you will need to have before you can enroll; pre-requisites are listed on the class detail page for each course.  AP credit in English does not exempt any student from WRITING 101.  History majors may count one AP credit in History toward the major.
            
^a CHEMISTRY: CHEM 110DL is only offered in the fall.  There is a section of CHEM 201DL (002) that is for first-year students and that is offered only in the fall.  In the Pratt School of Engineering, CHEM 20 will not satisfy the Biomedical Engineering chemistry requirement.  Biomedical Engineering students are required to take CHEM 110DL and 210DL, or CHEM 110DL and CHEM 201DL.
 For discussion of placement, see https://chem.duke.edu/undergraduate/placement-guidelines.

^b MATHEMATICS: Students who are interested in economics and social sciences and who are confident they will not pursue math, physics, chemistry, or engineering may take MATH 202 instead of MATH 212.  See www.math.duke.edu/first_year/placement.html for discussion of placement.  Note that AP credit in MATH was changed for the class entering in fall 2016 (a score of 3 on the Calculus BC exam no longer provides credit and a score of 4 gives credit for only MATH 21). 

^c PHYSICS: In Trinity College, prospective Physics and Biophysics majors are strongly encouraged to take at least PHYSICS 162L independent of their AP course credit.  In Pratt School of Engineering, at least ONE Physics course must be taken post-matriculation to satisfy the Physics requirement in the Engineering curriculum. Students receiving AP credits for PHY 25 and 26, must: a) take a Duke Physics course at or above PHY 153L; b) decline the AP credit for PHY 26 and take PHY 152L; or c) decline both AP credits and take PHY 151L and 152L.

^d STATISTICS:  AP credit only applies to students in Trinity College.  No credit is awarded for Engineering students and will not count toward the Bachelor of Science in Engineering degree.

In order to have your AP credits placed on your Duke record/transcript, you must have the AP Service send your scores to the Office of the Registrar at Duke.  To send AP scores to Duke, contact AP Exams, CN6671, Princeton, NJ 08541-6671; http://www.collegeboard.com/student/testing/ap/exgrd_rep.html ; 609-771-7300 or 888-225-5427.  Duke's CEEB number is 5156.
