Accepted but waiting for others

<p>Today I received an email from Rockefeller University's summer internship program saying I was accepted and asking for the dates I would be available to work. However, I also applied to 4 other internships that have yet to get back to me. I would like to do Rockefeller but I also would prefer some of the other internships if I got in.</p>

<p>I applied to RSI, Clark, SIMR, and a local one (tgen). I feel like those are almost all crapshoots for me but would rather do RSI or maybe Clark if I got in. I would want to do SIMR because Stanford is on my list for next year and I may develop a good bond with my research head. The letters of acceptance/rejection come out around April 1 for all of them. Does anyone have any suggestions for what I should do? I feel like I need to email Rockefeller back in the next couple of days.</p>

<p>Does anyone know much about Rockefeller? I have heard very fairly little about the program.</p>
