Also keep in mind that tuition usually increases every year.
If you have a full tuition scholarship, no matter how much tuition increases, you know that it is going to be covered.
if you get 30k/year tuition scholarship for 4 years
year one tuition is 40k, you pay $10k
year 2 tuition is $42k, you pay 12k
year 3 tuition is $44,100, you pay $14, 100
year 4 tuition is $46,305 you pay $16, 305over
the course of 4 years your tuition cost have increased $12,405. Room, board fees will also probably increase over the years.
