NPC’s are notorious for being old with info and also overly optimistic with merit/grants.
Also…remember that any “real” COA’s that you’re seeing now on the school’s website is for the CURRENT school year (2014-15)…so those COA’s will be higher in the Fall 2015…and every year after that.
I also would be very hesitant about over-paying for an aspiring PA. At this point, you really have no idea if the interest will remain or if grades and GRE scores will be high enough for admission later. Being pre-PA is a lot like being pre-med…lots of kids want to pursue, but many never make it.
