<p>BlusteryDayLover has a few good points. You are not going to close any doors by attending Bryn Mawr; worst case it will take a few more years (and $$$) to get to your goals. </p>
<p>The 3-2 program is usually not a good option because it requires very focused coursework from your first day on campus. (I have personally only met a single student who was on track to complete the academic requirements for the program. Then at the end of her sophomore year, Caltech announced a change of their financial aid policies, leaving her unable to afford the program. She eventually got an AB/MA in math from Bryn Mawr and is now happy in consulting, so it all worked out for her in the end.) Of course there are other ways to go into engineering from Bryn Mawr. Physics majors occasionally go to graduate school in engineering: a Bryn Mawr alumn who graduated two years ago is now studying robotics at the University of Pennsylvania, and a current senior has been applying to Master’s programs in aerospace engineering (though she probably won’t be able to go because $$$ didn’t work out). </p>
<p>I agree with the advice of everyone else on this board: follow your heart!</p>
