Presidential for many that I know was $25K, but that was a few years ago. It also comes with a 3.2 minimum GPA. Grants are need based. I know people that had an increase in salary and the grant was taken away. Grants are not guaranteed for 4 years. The Presidential Scholarship is guaranteed for 4 years as long as you meet the 3.2. The 40K does include room and board. Food is really expensive freshman year, but it goes down after that.
