Writing my resume...help!?

I'm doing my resume and I worked once in my life and I worked because I wanted to get into Vet School and I did. BUT right now I want to look for another job but I didn't have lots of experience 3 years ago when I worked for 2 months in a clinic. The only things I helped with back then was to clean kennels, did inventory, bathe an animal actually two, I did go in the surgeries with the vet but I was watching the doctor doing it and if there was a problem I called a technician... BUT now... I went back to school [I've been having problems with school but I always come back to take the classes I didn't make..right now is my second time I failed a class and I have to wait 6 months to go back to school in the meantime Im looking for a job] I learned lots of things this semester that I know I can do in a new veterinary clinic but is it ok for me to make a note at the end of my skills [experience] what can I write [IN MY RESUME]to let them know that i learned a lot of things and that i will be back to school....
