I see St Laurence and Wooster as pretty similar (don’t know their relative rankings) and probably a bit better than Earlham…which has also had some financial issues.
I would let St Laurence know of Wooster’s offer, but I agree with what austinmshauri said above…it’s not likely they will match it by giving you another $25k/year. But you can try.
Just be respectful, say I received this offer from Wooster, but would prefer to attend St. Laurence. Tell them what your family can afford to pay, and go from there.
