im a com/arts student rite now
truth is
u can double major
1 major in arts
but
ur arts major cannot be a eco/com related major e.g. international business
as for languages
it has different levels
beginners, intermediate, professionally etc...
professional is about the literary skill of a high school student in whatever language ur doing
u wont be perhaps able to read that country's say equivalent of shakespeare with ease, but u should be able to live and survive wifout a problem , write and read wifout much of a problem and wif a bit of practice and perhaps further professional tutoring, can work in professional fields.
