I got an admission offer on April 15. Before I received the offer, I got a mail from the program coordinator; " While the decisions for admissions have not been completed, I wanted to see if you were interested in applying for a graduate assistantship. If you are interested, please complete the attached application for GA and submit the completed form by Wednesday, April 13" But I didn't hear anything about funding after that. I sent inquire mail for two times to the program coordinator. No answer.. What should I do?
