I agree that you should go to Maryland. If you don't, you will always wonder what if.... It is a good program and a good fit. Plus you are super excited about going there. Accept and enjoy that you are done with this stage of the process!!
Oh, and congratulations!
I am coming out from lurking to join this thread. I am still waiting on Georgia State. I feel like it would be a good fit for me and I have connections in Atlanta that would make it a very attractive place to live. But I noticed that there are several acceptances already posted. I am getting so impatient and just want to know where I am going and move on. But I am holding out for that last school even though I am afraid that it isn't looking good. Patience is not a virtue that I possess.
