The Girl Genius Advanced Class was the name of a class offering by the Department of Almost Certainly True History at TPU, taught by the Professors Foglio and their associates, one of two classes about Agatha Heterodyne's history. It continued from where the 101 class stopped, to wit: , beginning with the Monster Horse Beastie. The class continued under that same name until the summer of 2007 when the beginning students caught up completely. At that point, the class was relisted in the TPU class catalog as simply Girl Genius and offered as a history of Lady Heterodyne's rise.
(Per the FAQ entry, when Girl Genius became a web comic, it was published in two streams, Advanced and Girl Genius 101. Advanced was new pages, 101 was the existing pages from the quarterly comic book, published at a faster cadence.)
