1 Students who begin with the CHEM 10181–10182 sequence and select BIOS as their major would complete the four-semester sequence with CHEM 20273–20274.
2 One of these courses must be a University seminar.
3 For premedical students, it is strongly recommended that the student take a 20000-level English literature course. This ensures that the student will be able to meet the standard medical-school admission requirement of two English courses. Medical ethics and biochemistry are also generally required or highly recommended.
4 While not required, many students choose to take a supporting 3-credit non-BIOS science course that counts toward the required 41 credits in their major.
Also, Biostatistics (BIOS 40411/42411) is highly recommended for all students planning on a health-related professional program or a graduate program, especially in ecology, environmental biology, or other fields of life science. A non-BIOS/Science elective can be any 30000-50000-level course other than those required, and approved by the director of undergraduate studies for the Department of Biological Sciences. Biochemistry (e.g., CHEM 40420) is especially recommended.
