Hi Joi - The first place to start would be to look into grants and scholarships available at your specific university and even within your department. You can try looking online at your school's financial aid office website or drop by in person to speak with the staff and ask for help identifying programs for which you qualify. After you apply for anything that is available through your school, start looking for any national opportunities. The U.S. Department of Education offers several need-based financial aid options you can look into (https://studentaid.ed.gov/sa/types/grants-scholarships). Grants and scholarships generally do not need to be paid back (unless you drop out of school), so those are the most desirable awards.
If you still find yourself in need of money and decide to take out a student loan, know that you don't have to take the full amount the government offers. Obviously you can't take more, but if they offer you $10,000 and you only need $3,000 for the year, you can accept only what you need!
A few tips to save some money while you are in school: Buy used textbooks whenever possible, limit your spending on eating out, live at home if possible, use public transportation instead of a personal vehicle if possible, take advantage of places that offer student discounts, and take advantage of your schools amenities like the gym and the library!
