*Note: these sample schedules represent only a few of many possible ways to move through the Astronomy & Astrophysics curriculum. Consult with an academic advisor to develop and refine an academic plan that is appropriate for you.
Curriculum
The Astronomy Department has adopted the following curriculum for the Astronomy & Astrophysics Major:
General Education (GE) Requirements
All students completing Astronomy & Astrophysics as their primary major must complete the GE requirements for a Bachelor of Science degree from the College of Arts and Sciences (ASC), which are detailed here. Students who began at Ohio State in Summer 2022 or earlier will follow the Legacy GE (or GEL), whereas students who began at Ohio State in Autumn 2022 or later will follow the New GE (or GEN).
If your primary major is in a different college and/or if your primary major does not result in a Bachelor of Science degree, then the GE requirements for your degree may be different. Please consult with the academic advisor for your primary major for clarification on your GE requirements.

Notes:
 Only one of Astron 1221, CSE 1222, CSE 1223, and CSE 1224 will be required. For students who have switched majors, Engr 1221 and Engr 1281H will also be considered acceptable substitutes.
 An acceptable substitute math sequence is Math 1151  1172  2173  2415  2568. Students with appropriate placement may also substitute Math 1161  2162 or Math 1181H  2182H or 4181H  4182H in place of Math 1151  1152  2153. Math 5520H may substitute in place of Math 2415  2568.
Math 1151  1172  2173  2174 may also meet the minimum requirements for graduation, but are not recommended for students who plan to go to graduate school in astronomy or physics.  Only one of Astron 5681 and 5682 will be required.
 Math 2255 Differential Equations and Their Applications is an acceptable substitute for Math 2415
 Only one of Physics 5401H and 5501/5501H will be required.
Double Major with Physics
Many students undertake a double major with Physics. Such a path increases the depth of preparation in physics and mathematics and is a good option for students intending to go on to graduate school in Physics or Astrophysics. If you are interested, check out the sample schedule for a double major in Astronomy & Astrophysics and Physics, linked above.
