The Ohio State University offers the Bachelor of Science degree in astronomy. To receive this degree, a student must fulfill the requirements of the College of Arts and Sciences and of the Department of Astronomy. Arts and Sciences requires undergraduates to complete at least 196 credit hours, although astronomy majors normally will exceed this number. Included in this total are courses in English, foreign language (Russian, German, French or Spanish is recommended for astronomy majors and Spanish is probably the most useful for observationally-oriented students), mathematics, social science, biological and physical science, arts and humanities, and history.
A Major Program, consisting of at least 40 credit hours of courses in physics, astronomy and mathematics, contains courses in which the student is required to receive at least a grade of C- on each course and an average grade of C. Courses usually included in the Major Program are preceded by an M in the listing below, while prerequisites to these courses have a P before them. Our recommended curriculum for the Bachelor of Science program is intended to prepare students for graduate study leading to a Ph. D. degree in astronomy; to be competitive for admission to most graduate schools in astronomy an undergraduate should have a grade point of at least 3.0 to 3.2, do well on the General and Physics Graduate Record Exam (GRE), and have some experience with a research project.
Modern astronomy is almost entirely the application of physics to the study the universe and objects contained in it. This study of astrophysics requires extensive training in physics and mathematics, as can be seen in the recommended courses for astronomy majors. The curriculum is highly structured, with lower level courses being required before taking the next higher courses, etc. The curriculum is also designed so that students interested in graduate study have completed most of their advanced physics coursework by the end of the third year and are better prepared to take the Physics GRE in the Autumn Quarter of the fourth year. In addition, most of the courses in a given subject must be taken in sequence. This means that a student who is delayed in taking the beginning math or physics courses can have graduation delayed and/or will need to attend summer school. Also, some upper level courses are offered only once a year, so that a student who is only one quarter behind the suggested curriculum may miss an offering of such a course and end up being delayed for a full year. Because of these conditions, care is required in planning the courses for a prospective astronomy major. The Astronomy Department's Director of Undergraduate Studies is also happy to meet with interested students to go over planning for courses (and for future careers). Contact information for the Director of Undergraduate Studies is provided below.
The suggested curriculum for a Bachelor of Science degree in astronomy is listed below. Math 151 is normally listed as a prerequisite for Physics 131; however, it is recommended that physics and astronomy majors take Physics H131 concurrently with Math 151, as shown on the curriculum. Note that the honors sequence in physics (H131, H132, H133) is given just once a year, starting in the autumn. A student who must postpone taking physics until a later quarter would take the non-honors 131-132-133 sequence. While some variations in the math and science courses are possible, such changes should be discussed with the Director of Undergraduate Studies. GEC stands for General Education Curriculum; these courses may be rearranged in the curriculum, although students are urged to take their beginning English course as soon as possible. Astronomy majors are eligible to use the "Drop-a GEC Option," and the suggested curriculum invokes this option to drop a Natural Science course. If an astronomy major decides to take Astronomy 171 and 172, then the "Drop-a-GEC Option" could be used for a different GEC, and the net increase in hours on the suggested curriculum would be five hours.
Students majoring in both physics and astronomy normally have the following courses in the astronomy major but not the physics major: Physics 596 and 664; Astronomy 291, 292, 350, 681, and 682. Some variation in these choices may occur depending on which option the student selects for the Physics major. The Physics Department website lists a Double Major Sample Curriculum. Note that Physics 596 also counts as the GEC third writing course. We encourage majors interested in graduate study in astronomy to consider a double major in physics and astronomy and to apply for our Summer Undergraduate Research Program and complete a thesis with Astronomy H783 their senior year.

Notes:
Students with superior preparation may be given credit for some of the lower level courses by passing a proficiency test in the relevant subject matter, so no one who already knows most of the material should have to sit through a course. Additional courses that would be useful for astronomy majors include Math 601, 602 and 701 (Mathematical Methods in Science), as well as CSE 202 (C++ programming). Students with superior mathematics abilities may take an accelerated version of the calculus and analytic geometry courses which cover the material in one or two fewer courses than listed above. Honors versions of some courses are available for particularly able students. Honors students in astronomy are especially encouraged to consider the advantages of participating in our Summer Undergraduate Research Program between their third and fourth years. In this program a student completes a research project in either theoretical or observational astronomy under the guidance of a faculty member and then enrolls in Astronomy H783 the following year to write a senior thesis. For students planning on graduate study, the experience, understanding and confidence that come from doing their own research are most valuable.
