Is it possible to major or minor in two different subjects at Arizona State University?
There are some courses and programs that allow you to do that so please look at the website for the most updated information or reach out to the Admissions department.
Minor can be any course that you take as part of your course, so almost all courses can be counted as multiple (or at least dual) minors.
I believe it depends on the field you are in. Try looking at the course handbook on the university website.
