If you have any interest in engineering, look into this program at BMC.

Have you contacted any profs in departments that interest you at Bryn Mawr or Haverford? The faculty at both LACs are willing to work with students who have special interests–that’s one of the benefits of going to a small LAC. Also, Swarthmore is part of the tri-co consortium with BMC and Haverford. Have you looked at the STEM departments there? My D (BMC grad) had a friend who took all of her major courses at Swarthmore. There’s lots of flexibility.
My D took one course at Penn–it’s not as close as Haverford (you can walk to Haverford), but it’s not difficult to get to Swarthmore. There’s a bus that goes to BMC, Haverford, and Swarthmore regularly–day and night (not all night, but fairly late).
