Actually it is stated that a max of 2 teams if not mistaken per game for each university/college.

http://www.pro-gamersarena.com/leagues/type-of-leagues.html

"Structure: each college and university may send 2 teams consisting of 10 players to enter the league." stated at the bottom.

Then again, it contradicts the previous post made by jealee:
"Defense Of The Ancients
CC = 3
College/U = FULL (MMU and LIMKOKWING together got 6 teams in this league)"

So how is it possible that there is 3 teams for both college? For one game?

Also the league structure is really confusing. I've red the website on the tournament structure and I find it confusing.

Furthermore I don't get this statement.
"COD 4 : Modern Warfare
College/U = 4 slots ( 12 teams reserved, first 4 teams make payment will get a place )"

If there is 20 teams for one league for one game,the statement above would say there is 4 slots left and 12 teams have reserved a slot for themselves. The first 4 teams who makes payments first will get a place,so what happened to the other 4 slots? Total would be 16.
