This particular major is shared by multiple colleges (Pitzer, Scripps, and Pomona, I think). So no matter which college you attend, you’re effectively getting the same major. It’s pretty seamless – for example, there’s no residence requirement that mandates a certain number of classes in the major taken at one’s own institution. (My D23 was accepted to both Scripps and Pitzer and was strongly considering this major, so unless things have changed in the last couple of years, that’s how it works.)
