Frequently Asked Questions

If you're unsure about where you're headed (Biology, Biological Chemistry, or Chemistry) you should take Bio 150, Chm 129, Math 131, and Math 133 in your first year. This will leave all options open to you. In the Fall of your second year you should enroll in Bio 251 and Chm 221. At this point (prior to the sprint semester of your second year) you will need to decide if you intend to pursue the Biology, Biological Chemistry, or Chemistry major. You must declare a major (download form from the Registrar; GrinnellShare login required), and prepare a 4-year plan, prior to registration for your 5th semester.

Planning for off-campus study requires careful consideration. It is to your advantage to begin the planning process in your first year. If you are planning an off-campus experience you should plan to be away during your 5th, 6th, or 7th semester. Biological chemistry and chemistry majors should talk with their advisers about when physics and physical chemistry should be taken in relation to an off-campus experience. 

Independent research is a central part of all three majors. It is required for chemistry major, and strongly recommended for biology and biological chemistry majors.

To be considered for honors in biology, graduating seniors, in addition to meeting the College's general requirements for honors (see Academic Catalog), must conduct an independent research project (either at Grinnell or elsewhere) and share their findings with fellow biologists in a departmental seminar. The award of honors is not based solely on grades and achievement in the classroom or lab. It signifies, in addition, an underlying commitment to the discipline as evidenced by participation in departmental affairs and activities (e.g., acting as a TA or mentor, or serving on the SEPC), including regular attendance at departmental seminars.

You can major in any of the three areas above (or any other at the college), but will want to take the following science courses before you take the MCATs (Medical College Admission Tests): Bio 150, Bio 251 and Bio 252, Chemistry 129, Chemistry 210 (formerly Chm 130), Chemistry 221 and Chemistry 222 Physics 131 and Physics 132 Math 131 and Math 133 (or Math 123 and Math 124) Students who wish to go on to medical school right after graduation should plan to take the MCATs in April of their 3rd year. Since this limits their options in non-science courses, most students take the MCATs at the end of their senior year and spend a year following graduation gaining work experience in a medical or research setting. Grinnell's Health Professions Advisory Committee can help you with these decisions.

If you are interested in becoming a teacher, you must contact the education department prior to preregistration in the first semester of your second year. To be certified to teach in a scientific discipline at the secondary level, you'll have to take 5 education courses in addition to major requirements. See the College Catalog for more specifics.

That's OK. You're here to explore your interests! Regardless of your potential career plans, it is to your advantage to discuss your interests with your adviser as soon as possible. Planning ahead isn't like signing a contract - it will help you to keep your options open.
