yeh it depends where you are too, everywhere is different. A vet thats known me since i was a little kid and i've always taken my cats to him wouldnt let me do anything. I basically cleaned the surgery for a week, it was pretty rubbish as a learning curve as i never even saw what he did! so i came out knowing nothing about what vets do and i was basically a free cleaner for a week, but hey! that happens, and it'll happen to all of us at one stage, the important part is sticking at it. Anyway im rambling, at another surgery i got to do lots and even got to diagnose stuff under the microscope (but that could have been cos im an immunologist already) and got to help with allergy testing, so that was really good experience. Basically, expect anything, it depends where you are, the main thing is to just do what you're asked to, and try and learn where you can. I think half of work experience is proving you can really stick at it!
