At Gettysburg College, the Chemistry and Biochemistry Department delivers a dynamic and hands-on education rooted in close faculty mentorship, interdisciplinary exploration, and real-world research. Students in both the Bachelor of Arts and Bachelor of Science degree programs gain deep exposure to fundamental and advanced chemical concepts while building critical scientific reasoning and laboratory skills.
One of the most distinctive aspects of the chemistry curriculum is the opportunity for students to engage in faculty-mentored research as early as their sophomore year. Whether through the Cross-Disciplinary Science Institute (X-SIG), summer research fellowships, or for-credit independent study, students often co-author publications and present at national conferences. The department also hosts regular seminar series, inviting prominent guest speakers and giving students a window into current trends and careers in chemistry and related fields.
Gettysburg's emphasis on undergraduate teaching ensures small class sizes and direct access to state-of-the-art instrumentation—tools typically reserved for graduate students at larger institutions. Courses integrate inquiry-based laboratory experiences, and upper-level electives allow students to explore topics like biochemistry, environmental chemistry, and inorganic materials. Whether you plan to pursue graduate school, enter the health professions, teach, or work in industry, Gettysburg’s chemistry curriculum provides a rigorous and rewarding foundation.
Major in Chemistry
Bachelor of Arts (B.A.)
The B.A. in Chemistry is designed to provide a solid grounding in chemical principles while allowing flexibility for students interested in combining their chemistry study with other disciplines. It requires eight chemistry courses, including foundational courses in general and organic chemistry, along with at least one upper-level elective that includes a laboratory component. Students also complete coursework in physics and calculus.
This degree is ideal for students planning careers in health sciences, secondary education, science policy, or technical writing, or for those pursuing a double major.
Bachelor of Science (B.S.)
The B.S. in Chemistry is a more intensive program that prepares students for graduate study in chemistry or professional careers in scientific research. It includes all B.A. requirements plus additional upper-level courses in physical and inorganic chemistry, advanced laboratory work, and a senior capstone seminar in chemical research. Students also take more advanced math (including multivariable calculus) and physics.
Students interested in earning an ACS-certified degree—a designation from the American Chemical Society that strengthens graduate and employment prospects—must also complete either Biochemistry I (CHEM 333) or Biochemistry II (CHEM/BIO 334).
Minor in Chemistry
The minor in chemistry offers a compact but meaningful experience in the chemical sciences. It includes general and organic chemistry plus additional coursework at the 200- and 300-levels, allowing students from other majors—such as biology, environmental studies, or health sciences—to add chemical expertise to their primary field of study.
Chemistry Placement Exam
Before enrolling in General Chemistry (CHEM 107), students must take the Chemistry Placement Exam, a requirement designed to ensure the best match between students’ backgrounds and course levels.
Who Takes the Exam?
This exam is required for:
Chemistry and Biochemistry/Molecular Biology majors
Biology majors pursuing the molecular biology track
Health Sciences (B.S.) and Environmental Studies (B.S.) majors
Any student planning to enroll in General Chemistry (CHEM 107/108)
Even students using General Chemistry to fulfill a general education lab science requirement must take the placement exam unless they’ve already received AP or IB credit for CHEM 107.
Timing and Format
Incoming first-year students complete the exam during the summer through the First-Year Dashboard. Returning students must take the exam before registering for CHEM 107.
The exam consists of 40 multiple-choice questions to be completed in 60 minutes. Students may use a scientific calculator and scrap paper (graphing calculators are not required). There's no penalty for wrong answers, and guessing is discouraged—the goal is to assess genuine readiness, not test preparation.
Placement Results
Based on the results, students are placed into either:
CHEM 107 (standard): for students with strong preparation in high school chemistry and math
CHEM 107-I (intensive): includes additional support through discussions and labs for students needing more foundation-building. This course grants the same credit as CHEM 107 and leads into CHEM 108-I in the spring.
Placement results are emailed to students before course registration opens, helping them make informed decisions about their academic path.
