I am a Vet Tech, though I went through a traditional 3 year college degree. I can attest that this course you are going through might not seem to be pertinant...but it really will end up being so. I had several classes that I thought were a waste of time, such as "Instrumentation." I even asked the teacher, why are we learning about this stuff when a Vet is not going to let me TOUCH a 30,000.00 machine??? Well, my first job out of college, part of my responsibility was doing preventative maintenance on thier 30,000.00 machines!!
So hang in there. It will all work out in the end. :)
