What happens after you've been admitted? You need to know that after you have been accepted by graduate programs, things are going to be very different, because the programs will now compete with each other to get you. They will probably call you and give you an interview either right before or right after accepting you, so be prepared. (Clinical programs tend to ask people to come out for a face-to-face interview before they accept you, so the pattern varies.) Be prepared for these surprise interviews by making a list of intelligent questions that you can ask when they call.
Just remember that getting into graduate school is largely a matter of luck. But if you've done background research to find out what it takes to get in, you will have a huge advantage over all of the applicants who have not. Most applicants, for example, won't have the patience to read all of the advice on this site or to look up all of the information that they should on the programs that they will apply to. I hope you're not among those applicants. Good luck!
