There are a number of ways to pay for college, but it’s not always glamorous. The best idea is to look for a scholarship. If your SAT scores are high, you could check out University of AZ and University of Alabama for starters.
One of the biggest costs are room and board. This requires an expensive meal plan too if you choose to live in the dorms. It’s something that parents usually pay for because they have money. It’s very difficult to pay for that on your own working 20 hours a week at Subway. It’s possible if you work 3 jobs over the summer and live on your savings during the semesters while working part-time. Living at home is a solid option if you can do it.
Another way to save money is simply spend your first 2 years at community college and live at home. You’d be taking the exact same classes you’re taking at a university for a small fraction of the cost. Your credits transfer directly to a university and you finish with the same degree as the rest of your graduating class.
