I know the majority of SC2 players are around the age of 20 (perhaps some a little younger/older) and while most of you probably have found your local scene I run into people every year who has/had no idea their NA college has one.
Collegiate StarLeague runs a huge SC2 tournament lasting all school year. Definitely check to see if your school played last season or if they marked their team as "looking for players" because that means they've been active within the last few months.
TeSPA is also holding an SC2 1v1 and 3v3 league, as well as a SC:R 1v1 league. Might want to check those out because it requires less people than CSL.
I represent UOIT/Durham College way up in the great white north and I'm doing my annual call for players. Good luck and have fun! UOIT/DC students: https://cstarleague.com/sc2/teams/2268
