Interdisciplinary major: how many credits are left?
An interdisciplinary major draws coursework from two or more departments rather than one, so meeting the overall credit requirement is usually not enough on its own. Most programs also set a minimum number of credits in each contributing field, which means you can be short in one field while the total looks healthy. This page checks both requirements on one screen.
Enter each field with its minimum and the credits you have earned, and the table flags the fields that fall short while the summary compares counted credits against the overall requirement. Courses that already count toward your primary major can often count here too, but programs cap how many credits may be double-counted. Anything claimed above that cap is removed from the total, and the amount removed is shown on its own line.
Per-field shortfalls use the credits you entered as they are; the double-count cap applies only to the overall total. Requirements, caps and the list of contributing fields differ by school and by program and are revised often, so take the numbers from your own program sheet. This page does not judge whether a proposed program will be approved.
Frequently Asked Questions
There is no fixed figure; each program sets its own cap. Enter the cap from your program sheet and the page splits the credits you claimed into the part that counts and the part dropped for exceeding the cap.
That happens when the field minimums add up to less than the overall requirement, which leaves a block of elective credits on top. You can earn those remaining credits in whichever contributing field suits your schedule.
It is treated as zero. Credits shared with your primary major then do not count toward the interdisciplinary requirement, and every credit you claimed as double-counted is removed from the total.
