Placement Exam Information
Yale offers placement exams in several subjects to help incoming students enroll in courses that match their academic preparation. Students interested in pursuing the MB&B major are encouraged to complete the Biology, Chemistry, and Mathematics placement exams.
The MB&B major includes introductory requirements in biology, chemistry, and mathematics. Depending on your placement exam results, you may be eligible to place out of certain introductory requirements. For a complete list of introductory requirements, please click here.
Students who receive placement and believe they may qualify for a waiver should contact the MB&B DUS and Undergraduate Registrar at MBBUndergrad@yale.edu. Please note that Degree Audit adjustments cannot be processed until a student has officially declared MB&B as their major.
