College degrees in the US are very expensive. When you plan on earning a degree, you need to do some serious budgeting.
First of all there are two budgets at stake. The cost of college itself, which is the most expensive part. Ideally your parents have saved for this expense. However, most students are not so lucky. They need to fund their college through financial aid, which very often means loans, and grants from charitable institutions.
The second budget is your cost of living, while studying. You can fist of all live a frugal life and only spend the absolute minimum to make you happy and a succesful student. Further you can try to hold a job that pays some of that expense.
