It is going to be harder but that is not to say there is no hope at all. I know social rejection sucks big time but you are not in a sorority now and if you don't try again you never will be so you are going to have to be emotionally tough and run the risk it will not work out. There are some things you can do to improve your chances. Study hard and get good grades. You don't want to be cut for bad ones. Get recs for every chapter. Get involved in a student organization. Sororities like that. Be on your best behavior for the rest of this school year. They won't give a bid to a tramp.
During rush I wouldn't be the one to bring up the fact that you went through rush this fall. They probably won't remember but if they do say you signed up but dropped out to concentrate on your grades. Keep an open mind about the chapters. This is very important. Your choices will probably be more limited than if you were a freshman.
The last thing, and I will probably get all kinds of abuse from the GC gang for this, is your looks. If you need to take off some pounds you must do it. Fat is a total killer in rush. Learn how to put on makeup like a pro. It can make a huge difference. Get a pro haircut you can easily reproduce. A $9.95 mall job won't do. Keep your eyes open on how the sorority girls on your school dress and do as they do. You want them to imagine you are one of them. You know from your first rush what they will ask you so practice your answers.
I can't think of anything else but good luck to you.
