• BY 105 (Biology of Plants)
• BY 106 (Biology of Animals)-no credit after BY108 or BY109
• BY 107 (Biology of Microbes)
• BY 108 (Biology of Invertebrates)-no longer offered, but students who took it prior to fall 2011 may count it.
• BY 109 (Biology of Vertebrates)-no longer offered, but students who took it prior to fall 2011 may count it.

Check the AP/IB section of the Majors' Handbook to determine if your AP or IB credit might fulfill the requirement for one of these courses.  Application of AP or IB credit to a specific organismic course will require you to successfully pass a departmental bypass exam for that course; these are offered in blocks 1,3, and 5 only.

2.  BY 208 (Ecology)

3.  BY 131 (Introduction to Molecular and Cellular Biology)

Check the AP/IB section of the Majors' Handbook to determine if your AP or IB credit might fulfill this requirement.

4.  BY 280 (Population Genetics) OR BY 231 (Genetics)

5.  Five approved Biology electives

• Three must be Biology (BY) courses at the 300 level or higher
• One unit of elective credit may be CH251, CH382, GY205, GY300, SC206, or SC301
• One unit must be an approved senior capstone course
• Any BY course except BY100 and BY104 may count as an elective
• BY101 (FYE) counts as one unit of lower-level elective
• It is possible to petition the department to ask for other courses to count as electives.

6.  Three units in Chemistry

• CH 107 (General Chemistry)
• CH 108 (General Chemistry II)
• CH 250 (Structures of Organic Molecules)

Check with your advisor to find out if AP or IB credit can fulfill CH 107/108 requirement.
NOTE: Graduate schools often require BOTH CH 250 (Structure of Organic Molecules) AND CH 251 (Reactions of Organic Molecules).

7.  One unit of calculus from:

• MA 125-6 (Pre-Calculus and Calculus)
• MA 126 (Calculus I)
• MA 127 (Calculus I and II, accelerated)
• MA 129 (Calculus II)

Check with your advisor to find out if AP or IB credit can fulfill the calculus requirement.

8.  One unit of statistics or mathematical modeling from:

• BY 220 (Biostatistics and Experimental Design)
• MA 256/BY 256 (Mathematical modeling in Biology)

Check with your advisor to find out if AP or IB credit can fulfill the statistics requirement.  Check with your advisor to find out if MA117 or MA217 can be used to fulfill the statistics requirement.

9.  Senior Capstone Experiences…During your last two semesters, you must ….

• Complete attendance at five Biology seminars, and summarize each in an abstract, and submit each abstract to your advisor no later than the first Monday of the block following the block in which the seminar occurred. After declaring the Biology Major, students can turn in abstracts during their junior or senior years.

• Successfully pass the Biology ETS exam or the Biology GRE exam.
• Register to take the ETS for Block 3 or early in Block 6, the only two times Biology offers the exam
• To take the Biology GRE in time to fulfill this requirement, you must take it in November or December and you must list Colorado College as a recipient of the GRE scores.

• Complete a senior capstone course in the last two semesters prior to graduation (options vary from year to year, but will always include BY499, Senior Thesis) in one of the following ways:
• BY 499 (Senior Thesis; required to graduate with distinction)
• BY 409 (Advanced Research in Biology)—IF it meets the requirements described in the section on “Senior Capstone, Part 3” in the Majors' Handbook.
• An approved Senior Capstone course.  The current list is: BY308 Advanced Ecology, BY365 Plant Physiology, BY366 Comparative Animal Physiology, BY378 Laboratory Investigation in Molecular Microbiology, BY410 Ornithology, BY412 Entomology, BY415 Evolution, BY421 Conservation Biology, BY440 Stem Cell Biology, BY443 Techniques in Molecular Ecology, BY463 Senior Seminar in Bacterial Pathogenesis, BY466 Developmental Biology, BY450 Seminar in Molecular Biology.
