My son entered Cornell his freshman year as an Environmental Engineering major and matriculated through CALS. Both CALS and the Engineering School have the identical major. If you matriculate through CALS, you actually have to satisfy the requirements of the Engineering school, NOT CALS. Therefore, the 60 or whatever the number is of CALS required credits do not apply to those in BEE(Biological or Environmental Engineering.). However, the AP score on Language arts exam I believe is different in the two schools. In this case, you would follow the required score for CALS. The main difference is that you pay tuition to CALS, which is about $15,000 less if you are a New York State Resident. However, my son transferred into the College of Engineering the spring of his sophomore year. He changed his major to Mechanical Engineering. Our tuition bill did not go up because Cornell meets 100% of need. So just because the tuition is higher, they said we could not afford to pay full tuition, so we still pay the same as if we were in CALS. Hope that helps!
