Fraternities to rush?

Incoming sophomore from UT and I’m trying to rush a fraternity and weirdly phi delta theta & alpha tau omega have “reserved” a bid for me ? I’m kinda confused since their rush week is in september but idk thats kinda too quick I think. Is it ? Idk if it’s like that with other fraternities at Utsa. Some of the other ones seem cool too look into and all have posted rush events except for one fraternity. Just curious what is y’all’s genuine opinion on the fraternities here at Utsa ? Thanks!
