You guys are so deprived >.>
My Math teacher in my last class of the day let's me get on RuneScape for a long ass time until it's time for me to leave.
No blocks or anything, and my math teacher made sure they can't block it because he told the computer lady that "RuneScape is a game in which *bewood*(real name not included) interacts with people and has to solve many math related problems in order to progress through the game. Last year in my computer class it also got him typing much more efficiently and he has told me this is where he learned his fast typing and math skills. Unless we have any problems with him using this site to do inappropriate things, it shall remain unblocked."
I was there when he said it to her >.>
