can a fraternity or sorority cut a pledge???

[iasw]

so i just accepted a bid to a fraternity, but our pledge class is really big compared to what its been in the past. so there were rumors going around that the brothers were going to cut about 10 pledges from the pledge class, so im a little concerned. are they allowed to do this or is this just a rumor? has anyone heard of having too big of a pledge class? i thought they would appreciate having more dues money but idk. sorry if this question isnt in the right forum.
