I believe that Oide Dasun is one of if not the friendliest and funniest teacher in G.C.M. He tells the most amazing stories during his double period buisness which have helped me survive double buisness many a time! Just don't get on his bad side though, cause when he gets mad, he gets MAD! But he rarely gets angry and always helps people out in class if they can't understand what he's saying. I personally would rate him 9/10. He is always fun to talk to outside of class too!
