Are you sure the $8k you received as a scholarship and the $7.5k grant on the NPC are two separate awards? Schools interchange ‘grant’ and ‘scholarship’ all the time; an athletic scholarship is actually a ‘grant in aid’ but everyone calls it a scholarship. NPC’s are often a year or two behind and haven’t been updated if an award increases with a new tuition increase. Just be sure you have 2 awards and not just one that’s been increased.
Great school and I hope you can make it work.
