sgopal2, there are 21 daily buses from Princeton University to the University Medical Center at Plainsboro - it’s a 15-20 minutes trip by bus and pretty easy to do (check NJ Transit Bus #655). Moreover, the new hospital is a vast improvement over the one in town - it’s a new state of the art facility, opened in 2012, that offers up to date equipment and opportunities.
Grade deflation at Princeton has been eliminated and research opportunities are available in all areas of science, including at the relatively new Neuroscience Institute. Princeton students have a very high acceptance rate into medical school (about 90% recently).
Duke is a wonderful school and I believe the OP would have a great experience there - I’m just trying to correct what I view as a few inaccuracies.
