In season 7 of Code Lyoko, won't they all be in college (Yumi goes off in season 6 to college)? How are they going to stop X.A.N.A. if they are in college? Unless of course, schools in France are like schools in Germany (schools in Germany have 5 years of high school [13 years total of non-college school], but even then, they would go to college in season 8).
