A grade of C- or better must be earned and revealed on your transcript for any course -- including the first semester -- to be counted towards the major or concentration requirements. The grade of P is not acceptable, but a course that was taken P/D/F may be counted if and only if the P is uncovered by the Registrar's deadline. (Please note that an exception is made for major courses taken in Spring 2020, when all courses were Pass-Fail).
Any exceptions must be approved in advance by an Advisor and you must receive an email notification of that approval.
Students may substitute Barnard College courses only with prior permission from an Advisor.
If you are planning to study abroad, please meet with your Advisor before you go. You'll need prior approval for any major courses that you take abroad.
I. Required Biology & Biochemistry Courses
- Both semesters of the introductory biology course (Barnard courses cannot be used for Intro Bio):
- Two Semesters of Biochemistry & Molecular Biology
***GS Majors may take UN2401/2 (contemporary biology) in lieu of Biol UN2005/6, with their Advisor's permission.
For a description of the differences between UN2401/2 and UN2005/6 see FAQ for GS Students, Q5. Transfer students who have completed 1 year of intro bio elsewhere must take UN2005/6 or UN2401/2 before taking upper level bio classes at CU. Exceptions will not be readily granted and require prior approval of the DUS, (Dr. M)
II. Required Chemistry Courses
- One Year each of General Chemistry & Organic Chemistry:
- UN1403 - UN1404 - General Chemistry I and II
- UN2443 - UN2444 - Organic chemistry I and II or UN2045 - UN2046 Intensive Organic Chemistry
- The following physical chemistry courses (two semesters):
- UN3079 - UN3080 - Physical chemistry I and II
III. Required Laboratory Courses
- One general chemistry lab:
- UN1500 - General Chemistry Laboratory or UN1507 - Intensive General Chemistry Lab
- One organic chemistry lab:
- UN2495 - UN2496 - Organic Chemistry Laboratory or UN2545 - Intensive Organic Chemistry Lab
- One of these upper-level biology labs:
- UN3058 - Project laboratory in microbiology
- UN3052 - Project laboratory in molecular genetics
- UN3500 - Independent Research Project, taken for at least 4 points
- At least one of these upper-level chemistry or biology labs:
- Chemistry UN3546 - Advanced organic chemistry lab
- Chemistry UN3085 or UN3086 - Physical and analytical chemistry lab I and II
- Chemistry UN3098 - Supervised Independent Reseach
- Biology UN3500 - Independent Research Project, taken for at least 4 points**
- An advanced Bio lab (UN3058 or UN3052). The same biology lab cannot be used to fulfill both requirements 3 & 4 -- you must take two different ones to fulfill both requirements.
- UN2501 - Contemporary biology laboratory plus one of the following
- UN3040 - Lab in Molecular Biology
- A 3 pt. Barnard lab course, with permission from Bio advisor
**You can take only one term of UN3500, but you usually learn much more if you work in the same lab for a more extended period. If you plan to do lab research, we recommend two terms of UN3500 (4 pts each) or one term + a summer of research in the same laboratory. (Even if only one term is applied toward the major.) SURF may be used in lieu of the lab requirement only if combined with one semester of UN3500; summer lab work under other auspices may not be substituted for SURF. Paid laboratory work may not be substituted for any of these requirements.
Note: Students who satisfactorily complete any of the following combination are considered to have completed all their upper-level lab requirements (3 & 4 above)-
- Two semesters of UN3500 for 8 credits total in the same lab.
- One semester of UN3500 for a minimum of 3 credits plus Surf in the same lab.
- One semester of UN3500 for a minimum of 4 credits plus one Project lab.
- One Project lab plus Surf.
- Two Project labs.
IV. Required Physics and Math Courses
- Two terms of Physics are required
- Physics UN1201 - UN1202 General Physics fulfills the requirement.
The 1400 sequence is recommended if you plan to take 3 terms of physics.
(Higher numbered sequences are fine if you have the background)
- Physics UN1201 - UN1202 General Physics fulfills the requirement.
- 2 Semesters of Calculus or Honors Math.
- For students with AP credit, A 4 or 5 in Calculus A/B in high school or a 4 in B/C calculus fulfills the requirement of one term of calculus toward the biology major. A score of 5 in B/C calculus fulfills the requirement of one year of calculus toward the biology major. (Students with these scores are exempt from some bio major requirements, as explained above, but will not receive AP credit if they take Calculus 1, or if they take no calculus at Columbia.) For more details, see the mathematics department web site.
V. Additional Course Requirements: Any three of these:
- Math courses:
- ODE (Ordinary differential Equation) or One additional term of Calculus or Honors Math beyond that used to fulfill the previous Math requirement (IV-2).
- Chemistry courses:
- GU4071 Inorganic chemistry (strongly recommended)
- UN4147 Advanced organic chemistry
- UN4102 Chemistry for the Brain
- Biology courses: Any Biology lecture course at the 3000/4000 level for 3 or more points.
The following are recommended. Prior approval is required for any course not on this list.
Note: SCNC & HPSC courses do not count towards the Major even if listed under Biology courses on Bio web site.
BIOT courses will not be counted towards the Major.
