As a member of the Class of 1992X, I feel it is important to ponder over some of the changes that have taken place or are about to take place in the veterinary college education process. The main reason for the changes being a drop in enrollment numbers 'first from 120 to 100 and then to admitting only 76 in my class. I'll explain the 'X' behind 1992 first. Our first semester in vet school we were enrolled in two classes--Philosophy 303X and Anatomy 305X. The X's stand for "experimental" We were not quite sure what that meant when we started. We figured either they didn't know quite what they were doing or they really did know what they were doing and we were a part of the plan. Now don't get me wrong, I am not against changes or trying to make progress but you have to admit it sounded kind of questionable. Anyway it wasn't long before we named ourselves the "Class of 1992X" and decided we really were being experimented with.
