How to respond to an unofficial PhD offer? I applied to 10 schools and have heard formally from 3, 2 rejections, 1 admission. I just received an email from another school (a very good one) saying that they are seriously interested in me, but would like to know if I am still interested in them. While I am very interested in this program, which is in my top 4, since I have not heard from the other 6 schools, I am not ready to make a decision. Does saying yes now mean I am committed to accepting their offer?
If they are still "seriously interested" in you, then that is not an offer on their side.

If you are still "seriously interested" in them, then that is not a firm commitment from your side.

Decisions are not binding until the ink is dry.
