We have two daughters in college and there will be 3 years where they are both in undergraduate programs. We found that, while WPI did not meet need for our youngest daughter for the first 3 years while our older daughter is still in school, the merit far exceeds need the 4th year when our oldest will be out. So averaged over 4 years it is about a wash. Our oldest is at a school that meets 100% need, but for her first year she was the only one in college so need was low.
