is it worth it to rush again

It depends on you. If your high school grades were bad or even not good, that can lead to getting released from houses. So if you now have great college grades the houses will know you can handle the work. Also if you didn't have any good friends in houses when you went through but now you do, that will make a difference. Sometimes all it takes is a couple of girls that are really enthusiastic about you to pull you in. But if everything is pretty much like it was when you rushed the first time, I'd say probably don't bother. You're going to get cut by the houses you want. Oh but if you dropped out with houses still left before and you're not going to do that now, then maybe you'll get a house. Good luck.
