Im 17 and starting my senior year along with taking all my pre reps throughout my senior year and working a part time job. How am I going to afford college?

Unfortunately paying for college in the United States is becoming more difficult, hopefully this will change with the upcoming election but as of right now I can only speak to what I did. I took out loans through the government for graduate school, and the company I was working for had tuition reimbursement which is something many companies do these days. For undergrad, the best bet is to do really well and win some kind of scholarship. If you look around, its surprising the number of people who find some sort of financial aid. Look into Co-op as well, you make good money that can help offset tuition costs.
