Hi,
My POI emailed me and offered a PhD position in his group. He also asked me that I prefer TA or RA?
First of all, how should I say thank you to him? It was a position that I liked much.
Second, I don't know to choose TA, or RA?! which you recommend?
Third, there is another position in another university I have applied, that I like it very much, too. I had serious talk with a professor there, and I will have an interview soon. If I receive a good offer from the second one, I think I will choose that, but I don't want to loose the other opportunity, cause I don't know even I will get an offer from the second one or not! What should I say in my response? Should I mention my condition?
