I applied to MPH programs not at my med school (I was actually in the MPH program at my med school as well and decided to finish my MPH somewhere else). I applied to Harvard, Hopkins, UNC-CH and Berkeley b/c these were the 1 year programs I found. I got in to 3/4 of the programs (rejected from Berkeley) so I didn't think it was overly tough to get in. Getting all the applications done during my 3rd was challenging.
