Undergraduate Major Manual:
02. Requirements for the Major

 

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

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)
OR For Class of 2009 or earlier only: BIOL 091 (assigned for AP or transfer credit) and either BIOL 121 or 122
(BIOL 091 cannot be combined with BIOL 101 or 102, see Section 6)

 

2
or
3

Two semesters of biology lab requirement:

2 semesters of lab or field experience, normally met by labs associated with BIOL 101 and 102 or BIOL 121 and 124.

(Students with AP credit, transfer credit or a Waiver for Introductory Biology, see Section 6.)

 

2 CU of chemistry, chosen from the following:

  • CHEM 1 with 51 or 101 with 53 (1.5 cu; first semester of introductory chemistry)
  • CHEM 102 with 54 (1.5 cu; second semester of introductory chemistry lecture)
    • or CHEM 15 with 55 (2 cu; honors chemistry; instead of Chem 1 or 101 and 102)
  • 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

2 additional CU of chemistry and/or physics, from the above list and/or the following:

  • PHYS 101 with 11 or 150 with 50 or 170 with 70 (1.5 cu; first semester of introductory physics)
  • PHYS 102 with 12 or 151 with 51 or 171 with 71 (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

2 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, other than a statistics course. MATH 114 is recommended for students who plan to take additional math courses.)

2

Biology courses at the 200-level:

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 - Cellular Neurobiology
  • Group 4: BIOL 230 - Evolution or BIOL 240 - Ecology: from individuals to ecosystems

After meeting the group distribution requirements, additional 200-level biology courses can be applied toward the 4 additional course units requirement below.

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

 

4
or
3

Four additional course units selected from:

  • Additional BIOL 200-level courses
  • BIOL 300, 400, or 500 level courses (listed in Section 6), or BIOL 140
  • Up to 2 courses given in other departments selected from the list in Section 4.

restrictions

    See Restrictions on CGS, Transfer, and Summer Courses for restrictions on transfer, 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. All BIOL 399 credits must be sponsored by a Biology faculty member who 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 group of 4 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 and

    (2) has one of the following:

    • Biol 091 credit (Class of 2009 and earlier only!) or
    • a grade of at least "B" in Chem 251 - Principles of Biological Chemistry.

    A Biology Major who has a Waiver for one semester of introductory biology will be required to take an additional 200 level biology course (a total of at least four 200-level courses, representing four different 200-level course categories, as listed above). In addition, a Biology Major who has a Waiver will be required to include a laboratory or field course as one of his or her intermediate or advanced courses for the major. (For additional explanation and a list of approved lab or field courses [which includes appropriate Biology Independent Study], see Advanced Placement.)

    The same policies apply to a Biology Major who is completing a Concentration, except that the required additional 200-level biology course for a student who has a Waiver will not necessarily result in a total of four 200-level courses. See your Concentration Advisor for specific advice.

    The same policies apply to a Biology Minor, except that the total number of required 200 level courses for a student who has a Waiver will only be three, instead of four.

    Total course units required for the major are typically 16. However, required total course units may be greater or less, depending on whether the student completes a Concentration (see Section 7), has AP credit, uses the Waiver Option, and depending on the specific courses used to satisfy the physics and chemistry requirements and the requirements for intermediate and upper-level biology courses. The student should focus on satisfying each of the major requirements and taking account of the stated restrictions; if these conditions are met, the total number of course units will suffice for the Major.
