So as April 15th approaches, it looks less and less likely that institution 1 will have a decision by Monday. However I have been accepted at institution 2. Now my question is should I accept the offer of admission from institution 2 just in case even though there might be a possibility of me not attending? I have no funding assigned to be as of yet. Also I spoke with the department chair a few weeks back and he said they'll understand if circumstances change after the 15th and I end up not attending even though I accepted. I understand that if I do this though, I am potentially taking another applicant's spot at institution 2.
This is for an MS program that might or might not lead to a PhD program at the same institution. The order in which each institute appears in my question is not significant, might be an unconscious thing though.
Help please
