Where was this movie shot?

There is a link on the left of every film title page called 'Filming Locations'.
In the case of this film, the locations were:

1) Bryn Mawr College - 101 N. Merion Avenue, Bryn Mawr, Pennsylvania, USA
2) Philadelphia, Pennsylvania, USA

It was shot at my grade school Waldron Mercy Academy in Merion Station, PA (a few miles outside Philadelphia) and it actually went co-ed in 1988! The director is an alum as well!
