Biology, B.S.

School of Natural and Behavioral Sciences

Program Overview

Whether you want to be a marine biologist, microbiologist, or zoologist—or any of more than a dozen other careers—you’ll find our Biology Department an exciting, supportive environment in which to broaden your knowledge, hone your skills, and perform cutting-edge research. You’ll be able to assist our faculty, who have active careers in laboratory-based research at the national and international level. If you are trying to decide between the B,S, or B,A, degree, the Bachelor of Science degree in biology requires more advanced science and mathematics courses than the Bachelor of Arts degree.

Biology, B.S.

Where You'll Go

With a background and training in biology, you could go on to become a scientist, educator, technician, or manager, to name just a few career options. Brooklyn College alumni with a degree in biology have gone on to work in health care services, education, hospitals, research, and elsewhere.

Similarly, to enroll in any course students must have completed the appropriate pre-requisite courses with a grade of C- or better. Any substitution of courses must be approved by the chairperson or deputy chair for advising. At least one course taken must be a writing intensive (W) course offered by the Department of Biology. Students who completed Biology 1080 and 1081 before fall 2010 may substitute them for Biology 1001 and 1002 in all degree requirements.

All of the following: Biology 1001, 1002, 3003, 3004, 3006 or 3007W, 3011.

At least 8 credits of the following: Biology 2001, 2002 or 2002W, 2010, 2020 or Psychology 2610, Biology 3020 or Psychology 3610, Biology 3030W, 3083, 4001, 4009 or 4010W or Computer and Information Science 2810W, Biology 4011, 4012, 4013, 4022, 4024W, 4025, 4026, 4027, 5000 or 5001 or 5003W or 5010 or 5014W, 5020, Chemistry 4581.

One of the following chemistry sequences, a), b), c), or d):

Mathematics 1201 or Psychology 3400.

Additional Requirements

Candidates for a B.A. degree with a major in biology must complete at least 60 credits in science and mathematics. Candidates for a B.A. degree with a major in biology must complete at least 18 credits in advanced courses in the Biology department or allowed electives in other departments as described above (not including Biology 1001, Chemistry 1100, 1050, 1200, 1201, 2050, 2060, 2100, 2200, 2201 and Mathematics 1201). These 18 credits must be completed with a grade of C- or higher in each course, and 15 or more credits must be completed at Brooklyn College. Specific course requirements for a B.A. degree are described above.

The following courses may be applied toward the 60 credits in science and mathematics:

Department Recommendations

Chemistry 3510 (or both 3511 and 3512) and 3520 or (both 3521 and 3522) and Physics 1100 and 2100 are required for some professional programs and are strongly recommended for prospective graduate students in biology. Students who anticipate majoring in biology must see a departmental adviser before the end of the sophomore year in order to plan their programs.

Student Learning Outcomes

  • Demonstrate a proficient mastery of basic biological knowledge through a sequential series of required courses in Microbiology, Genetics and Evolution.
