General Statement

Nature, its origins and its evolution, its strengths and its frailties, its order and its perceived disarray, constitutes the realm of study classified as science. Scientists search for interconnecting relationships and traits of order to understand the nature of our universe. Each new discovery provides additional knowledge and frequently enables the solution of previously perplexing questions. Often technology is able to transform scientific discovery into applications which are beneficial to our everyday living. Technology would be impoverished were it not for the new knowledge continually being sought by scientists. At the same time, science could not progress without the advances in instrumentation and techniques generated by technology. Thus, a symbiotic relationship exists between science and technology, a relationship which permeates the courses and programs in the college.

The departments of the College of Science are organized to respond to the needs of students for both general and specialized education in science in offering the Bachelor of Science and the Bachelor of Arts degrees in Biology, Chemistry, Mathematics, Physics, and University Studies. The former degree permits heavy emphasis in selected subject matter and closely allied fields, whereas the latter degree is designed for the student who desires a more broadly based education while still specializing in one of the sciences. Additionally, the college offers a Bachelor of Science degree in Applied Mathematical Science and Statistics.

For this reason, many students select a degree program in science to complete their prerequisite courses for professional study programs. The early admissions option to professional schools of dentistry or medicine in the biology degree programs provides the opportunity for a student to receive a degree in biology if they are successful in gaining admission to a professional study program in medicine or dentistry prior to completion of a regular four-year degree program. To receive the degree, they must complete all requirements under this program and successfully complete their first year of medical or dental school.

In addition to the Departments of Biology, Chemistry, Mathematics, Physics and Astronomy, and Statistics, the College of Science includes the Cyclotron Institute, a research institute that emphasizes fundamental studies of nuclear science in which both undergraduate and graduate students participate. The College of Science offers MS and PhD programs in various departments.

General Degree Requirements

Degree requirements for science majors are organized into:

  1. general requirements, including University Core Curriculum requirements and College of Science requirements;
  2. requirements of the major field of study;
  3. requirements of the minor field of study for those students completing a BA degree; and
  4. electives.

With the exception of physical activity and general elective requirements, courses taken to satisfy degree requirements must be taken for letter grades.

Students are responsible for selecting the courses in their degree plan and assuring they abide by Texas A&M University Student Rules in meeting all degree requirements. Each department has advisors who should be consulted in developing degree programs.

General Requirements

General requirements include those which are required in every degree program at the University. Please refer to these requirements defined in the University Core Curriculum and graduation requirements in foreign language sections of this catalog. Special guidelines should be noted in the following categories:

American History

U.S. history course 13
U.S. history course 13
Total Semester Credit Hours6

Three hours in history may be substituted by successfully completing the required four semesters of upper-level ROTC curriculum.

Government/Political Science

POLS 206American National Government3
POLS 207State and Local Government3
Total Semester Credit Hours6


Three hours in political science may be substituted by successfully completing the required four semesters of upper-level ROTC curriculum.

International and Cultural Diversity Requirements

The International and Cultural Diversity portion of the Graduation requirements may be fulfilled by 6 hours from the approved list of courses (see the International and Cultural Diversity requirements page). These courses may be in addition to University Core Curriculum requirements, or if a course in this category satisfies an area of the Core, it can be used to meet both requirements.

Major Field of Study

Each department sets its own requirements for the major. At least 12 semester hours in the major must be completed in advanced courses (300- or 400-level) in residence at Texas A&M.

Minor Field of Study

The BA degree requires a minor field of study or an area of emphasis for students pursuing teacher certification. A minor requires 15–18 semester hours in one discipline. Six of these hours must be advanced (300- or 400-level) courses. Students must contact the department offering the minor to determine course requirements. Students pursuing a BS degree may select an optional minor. Contact the department offering the minor to determine course requirements.  Students must declare a minor no later than the date on which they apply for graduation.


Electives should be chosen to enhance the student’s degree program and/or complete professional school prerequisites if not contained in required courses in the degree plan. Elective courses must be above the minimum level required in other areas of the degree program. For example, MATH 102 is not acceptable because it is below the minimum requirement of calculus. Also, introductory courses to another field of study such as BIMS 101 and AGLS 101 will not count toward degree requirements. Lower-level ROTC courses are not acceptable as electives. Please consult an advisor when selecting electives.

Curricular Options

Honors Program

The College of Science participates in the University Honors Program designed to offer the superior student special opportunities for academic work of a range and depth appropriate to his or her capabilities and greater intellectual interests. For further information, refer to the section regarding the University Honors Program.

Cooperative Education Program

Cooperative education enables students to gain practical work experience and a salary while completing academic requirements. During the four-year academic program, co-op students complete two to four periods of work away from campus, gaining experience through on-the-job training and thus improving their opportunities for future employment. The Cooperative Education Office provides additional information about this program.

Minor Field of Study

Each department in the College of Science offers a minor. Students interested in pursuing a minor in a field in the College should contact the department offering the minor.

Summer Internships

A number of programs are available throughout the country which offer summer employment to students interested in specific fields of study and training. Each departmental advisor has information pertaining to these programs.

Integrated Fast Track Bachelor’s and Master’s Degrees

The Department of Mathematics provides the opportunity for ambitious and talented students to earn a bachelor’s and a master’s degree within a five year period. Eligible students earn graduate credit during their undergraduate study which allows them to complete this option. Interested students should contact the Mathematics Department if interested in this program.
