Additional Information and Department Policies º¬Ðß²ÝÑо¿ÊÒ

Students are advised to complete µþ±õ°¿³¢Ìý1102 Biological Principles II or µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology and courses in chemistry for the major by the end of the sophomore year. Students planning postgraduate education in science or the health professions should note that graduate and professional schools may have additional admissions requirements in chemistry, mathematics, and physics. It is strongly advised that students consult with faculty on the design of their major and discuss the options of research projects through independent studies, fellowship-funded summer research, and honors projects. Students planning careers in the health professions should contact Valerie Bennett, director of health professions advising.

The biology department participates in the , and programs. Students majoring or minoring in biology may not also major in biochemistry or neuroscience.

With departmental approval, students are allowed to count courses taken at a different college or university toward the major. Normally no more than two transfer credits can be applied to the biology major and no more than one transfer credit can be applied to the biology minor. 

Advanced Placement or International Baccalaureate credits may not be used to fulfill any of the course requirements for the major.

Electives for the biology major or minor may be double-counted in a second department or program.

Grade Requirements

Only one D grade is allowed in courses required for the major or minor. This D must be offset by a grade of B or higher in another course also required for the major or minor. Courses that count toward the major or minor must be taken for regular letter grades (not Credit/D/Fail).

Information for Incoming Students

Most students interested in exploring biology at º¬Ðß²ÝÑо¿ÊÒ start by taking either µþ±õ°¿³¢Ìý1101 Biological Principles I or µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology. µþ±õ°¿³¢Ìý1101 Biological Principles I is the first of a two-semester introductory biology sequence.  Each year µþ±õ°¿³¢Ìý1101 Biological Principles I is offered in the fall semester and µþ±õ°¿³¢Ìý1102 Biological Principles II is offered in the spring semester, allowing students to explore 2000-level biology courses in the following year. µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology is a one-semester introductory biology course that prepares students to explore 2000-level courses in subsequent semesters. µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology is offered every semester.

Incoming first-year students who complete the biology placement exam and the quantitative reasoning (QR) exam receive one of the four recommendations below:

  • Enroll in µþ±õ°¿³¢Ìý1101 Biological Principles I
  • Contact Pamela Bryer to discuss placement (this category is reserved for those on the boundary of a recommendation of µþ±õ°¿³¢Ìý1101 Biological Principles I or µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology)
  • Enroll in µþ±õ°¿³¢Ìý1109 Scientific Reasoning in Biology
  • Enroll in a 2000-level biology course (a small number of students receive this placement; students seeking this placement should contact Professor Hadley Horch)

Incoming first-year students should take the biology placement and QR exams in the summer prior to matriculation.  AP/IB scores are considered in combination with information from biology placement and QR exams in recommending placements. A placement recommendation is required for a student to request a biology course numbered above 1099 during course registration.

If a student did not complete these exams in the summer prior to matriculation but wishes to enroll in a biology department course, they should complete the biology placement test immediately and inform Pamela Bryer once completed so that a recommendation can be made for them.
