Another one of mine is Caitlen, and she teaches Criminal Justice.

My entire school schedule

Mordekaiser
Teaches metals (Favorite class ever!).

Malphite
Teaches Geology (Hands bits of his own body as samples).

Twisted Fate
Teaches Math (The probability of us losing all of our money by the end of the day... 100%).

Graves:
Teaches Western History (The cowboys killed the card dealers. End of the school year).

Lee Sin:
Teaches P.E. (Just tell him you ran the mile and you're golden).

Fiora:
Teaches French (Get lunged at if you speak any English. Having mixed feelings about this class)

Garen: Teaches Swordplay (and if ur not quick enough u get whapped on the head with the flat of that huge sword)
Kat: Teaches Assassination (and one of the students is the dummy)
Janna: Teaches Reproduction (and we try on her :-) )

Ashe/Varus is in charge of the archery club.

Zyra teach natural sciens and I don´t miss a class
Caitlyn gives math and I work my way to be the teacher´s pet xD
Garen teach Demacian History and if you fell sleep you get punish whit 30 sec of spining @.@

Gambling and Card Tricks with Professor Fate. Best elective ever.

Law 101 with Professor Kayle. One time her sword suddenly ignited on it's own and caught fire to the room and we had to evacuate the building.

Mechanical Engineering with Professor Rumble. Pretty cool ****, but the last time a classmate even laid a finger on "Tristy" (thats what he calls his mech), he tazed them. And apparently, making any mention whatsoever of Professor Heimerdinger gets you kicked out of the class. ._.

Advanced Arcane Magic with Professor Xerath. A lot of students complain about how insanely friggin' hard it is, but i'm more worried about the punishments he dishes out...

Anthropomancy 101 with Professor Nasus. Quite possibly the sickest class i've ever taken...

Vocal Music with Professor Karthus. He looks likes he's never eaten a day in his life, but hey. The guy has a phenomenal voice.
