Undergraduate Major Manual:
02. Requirements for the Major

(These requirements differ slightly for students completing a Concentration. Please see Section 7 for specific information on concentrations.)

courses

CU

Introductory biology:

Track 1: BIOL 121 and BIOL 124 (lab course)

Track 2: BIOL 101 and BIOL 102 (or BIOL 121 and 122)
Note: BIOL 091 (assigned for AP credit) does not fulfill requirements in the Biology major.

 

2
or
3

Two semesters of biology lab requirement:

2 semesters of lab or field experience, normally met by labs associated with introductory courses.
(Students with credit for the departmental placement exams, transfer credit, or a waiver for Introductory Biology, see Section 6.)

 

Two cu of chemistry, chosen from the following:

  • CHEM 1 with 51 or 101 with 53 or 55 (1.5 cu; first semester of introductory chemistry)
  • CHEM 102 with 54 or 56 (1.5 cu; second semester of introductory chemistry lecture)
    • or CHEM 15 (1 cu; honors chemistry I)
  • CHEM 241 (1.0 cu; first semester of organic chemistry)
  • CHEM 242 (1.0 cu; second semester of organic chemistry)
  • CHEM 245 (1.0 cu; organic chemistry lab)

2

Two additional cu of chemistry and/or physics, from the above list and/or the following:

  • PHYS 101 or 150 or 170 (1.5 cu; first semester of introductory physics)
  • PHYS 102 or 151 or 171 (1.5 cu; second semester of introductory physics)

(Students interested in Graduate School are advised to take a full year of both physics and organic chemistry. Premeds should see: www.upenn.edu/careerservices/gradprof/gradprofmain.html)

2

Two cu of calculus and/or statistics, chosen from the following:

  • MATH 104
  • MATH 114 or 115
  • BIOL 446 or STAT 111 or STAT 102

(MATH 115 is recommended for students who do not plan to take further math courses, other than a statistics course. MATH 114 is recommended for students who plan to take additional math courses.)

2

Intermediate biology courses must be selected from the following groups:

Track 1: must take four courses from four different groups

Track 2: must take three courses from three different groups

  • Group 1: BIOL 202 - Cell Biology and Biochemistry
  • Group 2: BIOL 221 - Molecular Biology and Genetics
  • Group 3: BIOL 215 - Vertebrate Physiology or
    BIOL 251 - Molecular and Cellular Neurobiology
  • Group 4: BIOL 230 - Evolution or BIOL 240 - Ecology: from individuals to ecosystems

All Biology Majors are strongly encouraged to take BIOL 221, since molecular biology and genetics play a central role in modern biology.

or
3

Four additional course units selected from:

  • Additional BIOL 200-level courses
  • BIOL 300, 400, or 500 level courses (listed in Section 3)
  • BIOL 109 or 140
  • Up to 2 courses given in other departments selected from the list in Section 4.

Students are encouraged to seek out advanced courses covering topics of current research interest. Such courses often have small enrollments.

Students will take a total of 16.0 cu to meet the requirements for the major. Most relevant biology courses are 1.0 cu, but BIOL 251 is 1.5 cu and BIOL 476 is a 0.5 cu course.

restrictions

  • See Restrictions on LPS, Transfer, and Summer Courses for restrictions on transfer, LPS (formerly CGS), and summer courses, and Advanced Placement if you have or are seeking Advanced Placement Credit.

  • All juniors must meet with their major advisors during the Spring semester prior to registering for classes. Any junior who is not cleared by their advisor will be placed on registration hold.
  • For a Biology major with a second major, at least five of the ten course units of Biology courses must be unique to the Biology major and may not be courses that are counted toward the student's other major or to other minors.
  • 1.0 cu of BIOL 399 may be taken for the major. A Biology faculty member must oversee any BIOL 399 and is responsible for approving the initial proposal and the final paper. In addition, students may count 1.0 cu of BIOL 499 toward the major, provided all of the other courses for the "four additional courses" are Biology Department courses. If a student wishes to count courses from outside the department toward the "four additional courses" requirement, then the student may only count one semester of independent study toward the major and can count the other semester as an elective.
  • BIOL 446 may be counted toward the requirement for "four additional courses" or toward the math requirement given above, but not toward both.
  • All requirements must be met by actual course credit; exemptions or waivers from other departments do not satisfy the requirements for the Biology major.
  • A minimum 2.0 grade point average for all courses taken to satisfy the major is required in order to graduate as a Biology Major. (You may have a "C-" or "D" in one or more courses, but your overall average in the major must be at least 2.0.)


waiver option

    A student may apply for a wavier for one semester of introductory biology if he or she

    (1) has grades of B or better in at least two semesters of chemistry taken at Penn,

    (2) a grade of at least "B" in Chem 251 - Principles of Biological Chemistry and

    (3) has taken (or is currently enrolled in) Chem 241 - Organic Chemistry I

    A Biology Major who has a waiver for one semester of introductory biology will be required to follow all requirements for Track 1 with the waiver counting in place of BIOL 121. In addition to the four 200-level courses from the different 200-level course categories (see list above), students with a waiver must take an additional course at the 200-level or above for a total of five "additional courses" (see list above). In addition to BIOL 124 (a requirement of Track 1), a Biology Major who has a waiver will be required to include a laboratory or field course of at least 0.5 cu as one of his or her intermediate or advanced courses for the major (see a list of approved lab or field courses in the section for Advanced Placement) in place of the lab portion of BIOL 121.

    The same policies apply for those with a wavier who intend to complete a Concentration, except that the required additional biology course will not necessarily result in a total of five additional courses. See your Concentration Advisor for specific advice.

    The same policies apply for those with a waiver who intend to complete a Biology Minor, except that the total number of additional courses will be three instead of two.
