I just looked at Harvard’s website. They advertise around $67K per academic year. The chart is bogus.
If you have a kid with a good GPA and test scores, there are colleges that will give merit scholarships from a few thousand to full tuition to a full ride. Those are mostly in the south and Midwest, but definitely worth the searching if you want to cut the cost down.
If you have a HS junior make sure they take their SATs or ACTs this spring. And start searching for colleges over the summer. If you have a sophomore, have them study for the PSAT. There are some automatic full rides for high scoring kids.
