Spoilt For Choice!

How exactly does one outway the choices of one specialism for another?
No, seriously i'm actually asking this question to anyone who may have any hint of an answer. When i look back on the year and a half i have been in the course and see that most of the work i have done on every production seems to be sound related in one way or another. This came to my attention a couple of months ago and i feel like its been bugging me ever since. Of coarse it is my fault for volenteering myself for the position and role of sound operator for most of these films, but it has now become a regular fact among the class that i am the guy to do sound for any production. This is not exactly how i imagined doing the course, although with every other factor in the academy i seem to be enjoying every minute of it. The only problem seems to be the position i have put myself in isn't exactly ideal for the aspirations that I have been feeling lately for the likes of cinematography.
It's hard to judge on either of my choices considering i have had no experience in the field as a cinematographer, and the kind of sound work i am interested in pursuing is that of design, in which i have also had no experience.
I suppose it's time to start climbing out of that whole and getting myself onto jobs that allow me to test my abilities and assist my judgment of what i want to choose in a couple of months time.
Fingers crossed my classmates overlook the original concept of sound and give me a chance to see what i can do in the role of cinematographer.
Only one way to be sure...
