Biology Major (B.S.)

The Bachelor of Science program is designed for students who intend to continue graduate study in biological or health sciences.

Only courses with 3 or more credit hours will count as biology electives towards the major/minor or as allied sciences

Departmental Requirements

  • BIOL 101 & 101L/102L (102L can be taken in place of 101L) – gateway course, with a C grade or better in BIOL 101
  • BIOL 201, 202, and 205 (the core courses)
  • One organismal structure and diversity course chosen from 271/L, 272/L, 273/L, 274/L, 275/L,  277/L, 278/L, 279/L, 471/L, 472/L, 473/L, 474/L, 475/L, 476/L, 478/L, 479L, or 579/L
  • Four biology electives numbered above 205 (not including 213, 291, 292, 293, 296, 495), at least two of them with a laboratory. At least two courses out of the five courses (four electives and one organismal course) must be numbered above 400 (not including 692H)

Additional Requirements

  • CHEM 102/102L, 241/241L, 261, 262/262L
  • PHYS 104/114 and 105/115, or 116/118 and 117/119
  • Two additional Allied Science courses (courses in biology, other natural sciences, or mathematics)
  • Students must fulfill all General Education requirements (Foundations, Approaches, and Connections) with these restrictions and additions:
  1. Foreign language: through level 3
  2. Foundations: Quantitative reasoning: MATH 231, and one of the following: MATH 232, COMP 110, 116, STOR 155, 215
  3. Approaches: Physical and life sciences: CHEM 101 and CHEM 101L
  4. Enough free electives to accumulate 123 academic hours
  5. At least 18 credit hours of C or better in Biology courses. Note that only biology courses that count toward the major can fulfill this requirement, and that BIOL 101 does not count toward this requirement.
