Upward Bound is a government funded education program. High school students attend a camp for roughly six weeks out of the summer to take classes that will help them throughout the school year. For instance, if a student is planning on taking chemistry in the upcoming year they can take chemistry during the summer and it will cover the most difficult topics so they will be farther ahead during the school year.
This program is free to the students who attend because it was designed to help disadvantaged children have a better chance to attend college. In order for the students to qualify for this program they must be in the first generation of their families to attend college and their families income must be below a certain declared level.
As you can imagine, being an educational program funded by the government they do not have much money. For even more information there is a link to the right of this page.
