I went to one of the schools you linked to. I ended up paying less than half of the quoted price and I had no financial aid or scholarships. My school's websites makes significant assumptions, such as assuming that you stay in the dorms (the dorms cost over twice as much as the average rent in the area) and that you buy every single recommended book brand new. Also, I don't think its fair to include things like room and board in the cost of a college education, as that is something that one always has to pay.

It is possible to earn enough money with a summer job (or part-time job during the school year) to significantly reduce the amount of debt you have to go into in order to afford a college education.

If you take every AP there is and also have a nice story about having 11 siblings, many schools will accept you with generous aid.

Also if you put away the money from the chores it may add up to something.
