rushing

I am a legacy to 4 EX men and pretty sure I'll get a bid just because of that.

But I'm also gonna look at other chapters and pick which one is the best for me (I would prefer to continue my legacy though).

So if I get a bid from Sigma Chi and decide I hate my pledgeship or get cut, can I accept a bid from another fraternity.

I'll make it a bit more clear.

I get a bid from Sigma Chi, Chapter A and chapter B.
On bid day I pick Sigma Chi and I become a pledge.
A week later, I decide EX isn't for me and drop my pledgeship.
Is their a possibility to accept a bid from A and B and catch up with the pledging?
