Congrats on getting into college. First, start with getting the projected amount of tuition, fees, book, etc for your first year from student accounts at your school. That will give you an idea of how much it will cost to attend school per year and how much (scholarships, loans, grants etc) financial aid you will need.
I would set up time with a financial aid officer at your school and show them your projected cost of study per year. They are the ones who set up your financial aid package on a yearly basis. They will be in a better position to give you an accurate amount of loans required to meet your tuition payment obligations.
Best of luck to you.
