My whole application I talked about wanting to do FM and focus on childhood development for underserved communities. I did research in this and lots of volunteering etc. It was the whole theme of my app.
HOWEVER during my gap year I have been doing a neuroscience research year and was able to shadow some neurosurgeries and talk with a couple neurosurgeons and I have become really interested in doing pediatric neurosurgery.
I just got my first A (!!!!) to my top choice. And they have several accelerated 3+X programs, including FM, neurology and neurosurgery. I emailed the program coordinators for all three of these. The neurosurgery coordinator emailed me back asking if I had expressed interest on my secondary application for the program I said no. (But I did talk to one of my interviewers about my budding NSGY interest though when we discussed my research year, and he encouraged me to apply.)
Now I'm nervous that if they realize I'm interested in neurosurgery as well, that they could rescind my acceptance if my app seemed kind of misleading like I only wanted to do FM. Could this potentially happen, or am I just being really crazy????
