I received an official PhD offer from University A on Jan 30 (15 days ago).
In an interview with the faculty from University A, they asked me where A stands among my applications. I honestly replied that A was among the top 3 universities and said that I need to hear from the other two schools before making any decision. I also expressed that it would be hard for me to make the decision before hearing from the other two schools from my top 3 shortlist. The offer from A arrived soon after the interview (obviously).
Today a professor from University A sent me a very short email asking if I had questions or I was close to making decisions.
Is he implying that I should hurry up?
I have not sent them any email since the offer as I had nothing to update. The offer follows the rule of April 15, but the school would offer me a small amount of fellowship (which I don't care) if I accept before late February. The other two schools just interviewed me several days ago and I would expect to hear from them soon.
How should I politely respond?
