Making your Way through the Biology Curriculum

A total of 37 biology credit hours are required to complete the biology major. A small number of biology courses are required of all biology majors. These courses are Principles of Biology I and II (BI 120 & 122), Biological Investigations I and II (BI 121 & 123), and the senior Biology Capstone (BI 480). The BI 120-123 courses serve as prerequisites for all other majors-level biology courses. Beyond these required courses, the biology curriculum affords students a fair amount of flexibility in completing the major requirements. Please visit the Major in Biology page for a complete description of the requirements for the major.

Your First Year

The vast majority of incoming freshman biology majors take a standard suite of courses during their first year of study. Students typically enroll in the following:

Fall Semester Spring Semester
BI 120 Principles of Biology I (3 cr.) BI 122 Principles of Biology II (3 cr.)
BI 121 Biological Investigations I (2 cr.) BI 123 Biological Investigations II (2 cr.)
CH 105 General Chemistry w/ lab (5 cr.) CH 106 General Chemistry w/ lab (5 cr.)
FYS 101 First Year Seminar (3 cr.) FYS First Year Seminar (3cr.)
Foreign language (3-4 cr.) OR Core requirement
(3 cr.)
Foreign language (3-4 cr.) OR Core requirement
(3 cr.)
Total 16-17 Credits Total 16-17 Credits

Please note that both the Biology and Chemistry courses are full-year sequences that must be taken in order and that they are not offered out of sequence; i.e., BI 120, BI 121, and CH 105 are only offered in the fall semester. Therefore, sitting out of either course in the fall means that you must wait until the summer or the following year to begin the sequence (CH 105/106 can be taken in the summer but BI 120-123 cannot). 

There are occasions when it is advisable for an incoming major to take courses other than the standard load.  Your advisor will help you choose alternate courses if necessary.

Beyond your First Year

Once you have completed BI 120-123 with C- or better, you may begin taking 300-level biology electives.  Nearly all electives offered belong to one of three groups or categories within the major. These groups (Genetics/Cellular/Molecular, Evolution/Ecology/Behavior, and Organismal) contain courses categorized by broad topic areas within the field of biology. It is recommended that you attempt to take at least one 300-level biology elective each semester following your freshman year. You will need to complete six electives distributed among the groups with a C- or better to meet the requirements for the biology major.  

Biology majors interested in post-graduate study in the health professions or graduate training in biology are strongly encouraged to complete a full year of Organic Chemistry (10 credits) and a full year of Elementary Physics (10 credits). The majority of biology majors complete Organic Chemistry in their sophomore year and Physics in their junior year although it is not mandatory to follow this schedule. Your advisor will work with you to determine the best schedule for your circumstances. 

All biology majors must complete the Biology Capstone course in their senior year. 

It is important to remember that as a student of Butler University and the College of Liberal Arts and Sciences (LAS), there are course requirements outside of your major that you must also satisfy to graduate.  You must complete the University Core Curriculum requirements as well as the LAS foreign language requirement (minimum requirement is two courses at the 200-level or above). Biology majors are encouraged to work to complete their foreign language requirement starting in their freshman year. Courses required for the Core Curriculum need not be taken immediately but, rather, it is recommended that you schedule them throughout your time at Butler.
