Schools

Early in the story, all the major characters went to Neopia Central Junior High. Now there are so many more characters - not to mention more schools - that it gets easy to lose track. Here's a guide so that you don't put people in classes with characters from the other end of Neopia. (The dates are in parentheses, starting at the beginning of the series; characters who no longer go there are in italics.)
