When I was a senior I had the basic senior dream. I would move out of my parents' house, be on my own, the basics. When I applied for financial aide that dream went right out the window. I did not receive any grants. I had to pay for school out of my own pocket and college is expensive.
Even though I go to Rend Lake it still takes a huge chunk of money for classes. I was silly in high school and didn't save money like I should have and I regret it to this day. I am learning responsibility though.
My advice is save everything you can, ask for help from your parents to save ( they will love to help you), and don't try to grow up too fast. You are still young. Enjoy life but be responsible at the same time.
