There are many types of loans or scholarships you could apply for which can get you through college without assistance from your parents. Many different organizations offer scholarships, and schools also offer scholarships and grants. Fill out a FAFSA which will help identify which aid you are eligible to receive. If you do not get enough financial aid from your school or independent scholarships, you can take out private student loans, which will need to be paid off after you graduate from college.
Chelsea recommends the following next steps:
I'd say continue to apply for scholarships and grants. Outside of that, I helped pay for the majority of my college education by working as a freelance writer. I got connected to my first customers as a college sophomore and then began building up more customers as my first few customers were happy with my work.
I also completed an accounting internship with PwC during my junior year! Look into the accounting program at your school and see what clubs you can join, because my internship with PwC led to a full-time job offer for me upon graduation. Attending career fairs at your school and seeing what kind of opportunities are out there is a great way to explore some great careers while putting some extra change in your pocket. If you have business advisors on campus, they tend to be great sources of knowledge for getting your foot in the door for your career of interest. The business advisor at my alma matter knew many people at PwC and had been working as an advisor for over 20 years.
In addition to applying for scholarships, which the answers above have described, you can also look for opportunities to work part-time during college. I worked about 20 hours a week making $15 per hour during my college career and while this certainly didn't cover all of my tuition costs, it greatly helped with living expenses. Tuition is the biggest cost and you can't avoid that without receiving a scholarships but it may be worth to look into state schools that offer lower tuition rates for residents.
A great way to save money is to attend a Junior College to get your basic classes done. It is considerable cheaper, you can usually live at home, and you can transfer your credits pretty much anywhere.
