So why are you going to University?  To get you qualified for a future job, or just out of interest?
If the former, you really have to picture yourself what you think you'll be doing, as well as perhaps consider the job market and prospects for that field.
Not sure about over there, but it's easy to switch majors and stuff here, however you may waste some time and money on courses you don't need for the new major.

EDIT: so I assume you're studying for job prospects - well what can you really consider yourself being in relation to the above choices?
There also may be the possibility of dual-majoring (check your Uni).
