Mine had studied for double majors, so his loads were heavy. Plus a study abroad semester( had to finish all required courses in 7semesters), frequent travels for national meetings and competitions, special oversea programs, being a head for major student organizations and clubs, and GPA requirement for a merit based scholarship, that's a lot on his plate.
However, he had got well paid internships every summer in college yrs, more than enough to cover his summer travels and living cost on campus.
