I applied for the fall here and would like to rush in the fall since I wouldn’t know anyone, would houses like Beta, FIJI, or maybe even Signu give me a bid?
If you mean you’ll be entering in the fall as a sophomore, rushing will be a little more difficult. Sophomores are given bids much more rarely than freshman, especially at “top” houses like Beta and Fiji. SigNu you’ll stand a better shot.
Really helps if you have a personal connection within the houses already though who can help get you involved in the rush process and vouch for you.
