She should do that ASAP. Like before holiday break if she can, at least start the process with an email to both. Sometimes the department web site has info on SA options as well, my D’s did, even with a “here’s how you might schedule courses over 4 years so you can study abroad” type section.
My D had 2 very tough courses to take abroad - which were for her major - and she balanced them with 2 relatively easy elective courses, one having to do with the culture of the country she was studying in. It can be done at many schools, especially if the school places great value on students studying abroad.
If that turns out to be truly impossible, she might investigate funding for out-of-semester study abroad or research. D’s done that sort of thing as well.
