1x11 - Code Lyoko

Jeremie learns that he has to take a test. If he passes, he'll get transfered to a new school and nobody will be able to stop XANA. Speaking of which, XANA takes control of a pack of rats. The rats attack the school and makes it nearly impossible to move around. Ulrich, Yumi, and Odd get Jim, Sissi, and everyone else to the roof and then proceed to the lab. Ulrich and Odd are virtualized, while Yumi controls the supercomputer. Does the team stand a chance with Jeremie temporarily gone?
