It is appropriate for your student to contact their AO at these colleges and ask how they are calculating GPA for the merit grid/award chart. (First, make sure the website doesn’t spell it out.)
Since many merit giving schools don’t have a merit grid, merit hunters often have to send in more apps on average, because affordability isn’t known ahead of time. Some NPCs do include merit aid, so run those. Some schools will also do merit/financial aid pre-reads, so something else to check on.
It looks like you’ve received some good college suggestions on your chance me thread.
