Zoey 101: Curse of PCA

S1 E4: Zoey and the gang have a tough test to study for -- so tough, legend has it, that Charles Galloway, a former PCA student, lost his mind taking an exam from the same teacher.  He ran away into the mountains, never to be heard from again.  After Lola finds a cute but spacey boy named Lafe to be their guide, a skeptical Zoey and Chase join their friends on a journey to see if the legend is true.  Unfortunately, the legend proves far too real, and the kids awaken the ghost of Charles Galloway, who begins to haunt them.  Now they must use their smarts to rid themselves of Galloway and restore order back to PCA.
