I pursued a Masters of ID after an undergrad degree of French & Econ. My opinion on this is mostly from the undergrads at Drexel Univ. They felt like they were getting the college experience as much as their high school friends at other schools. Mostly because they were in a city, near other colleges (Penn, Moore, U of the Arts). They did talk openly about being far more stressed than even their engineering friends. The workload for ID programs and IArch programs is intense. I can't think of a single undergrad in the program who was in a sorority. Mostly those were the girls in the fashion & merchandising program because they had time on their hands. We did have some students who were very busy with athletics, but you could see the impact on their projects. They just didn't have the time to devote to live in the studio working.
I would say that she should look in magazines and websites to pick out a few designers/firms that she admires. Then check out LinkedIn to see where their employees graduated from. People are always more likely to support alums and in this field, she'll benefit greatly from getting her foot in the door.
I would also suggest she seriously consider doing a study abroad through DIS www.disabroad.org/. They are highly regarded in the field and having studied there myself, I can tell you their programs are top-notch. She'll make a lot of life long friends and great contacts.
Best of luck to you!
