It is very difficult to find scholarships to cover all your personal expenses so most students have to work during the summers. For lists of outside scholarships, check your high school websites, local civic groups, the college FA office. You are correct that they are even more difficult to find for those past high school graduation. See if your department at school has some. But again, these may reduce your award from Emery because schools that meet financial need expect you to work for some of the funds. Many people would rather babysit for their sister or take care of an aunt, but the school is not going to expand their financial aid for those who choose to do so.
My kids didn’t earn $3000 this summer and they are going to have to do something about it (spend less, work during the school year). It wasn’t that they just sat around, one worked at a girl scout camp that didn’t pay much, the other painted her grandmother’s house and helped with a lot of other odd jobs. Both good things to do, just don’t pay much. Their schools didn’t give them one red cent extra for having good intentions and helping others.
