<p>i applied to jhu and rice environmental engineering at the last minute. on jhu and rice's supplement, i marked my chosen major as enviromental engineering. both schools use common app, and i already submitted my common app to other schools, so i couldn't change anything...in my personal statement, however, i included a few lines about how i wanted to pursue computer science (i applied in this field to 4 other schools). how much is this lack of foresight gonna hurt me?</p>
