- Most students interested in biology elect to take Bi8 and Bi9 in their first year, to open access to the widest range of biology electives.
- Bi 10 or Bi1x is not required for the biology option but is commonly taken by biology students to meet the Institute introductory laboratory requirement.
- Prerequisites listed for individual biology courses are advisory, not compulsory. They indicate the kind of background that is assumed for the work level of the course. They may be waived if the instructor gives explicit permission.
- BE 25 is strongly recommended for students interested in post-graduate work in biology, as physical chemistry is required by most graduate programs.
- Additional courses of potential interest to biology majors include Ge 11 b, BE 159, BE/APh 161, BE/ChE 163, BMB/Ch 178 and advanced geobiology courses.
- Undergraduates are generally welcome to take 200-level courses with the instructor's permission or strong preparation, unless otherwise indicated.
