<p>It doesn't matter.</p>
<p>The savings can be a lot more than $2000 a year if you go to CALS and you're in state. However, If you qualify for financial aid, there might not be any difference. To give you some idea of what aid to expect, my family has an income of about $85,000, and there are 5 in my family. The grants I receive from Cornell are slightly more than the difference in tuition between CALS and CAS, so I chose to go to CAS.</p>
<p>Either one is great for bio, since it is the same bio program. However, if you think you might want to double major or take a minor in a different area. . .for instance my student advisor is a double major in psychology and biology. He has his choice of several med schools, and it worked out great for him.</p>
<p>If you have interests outside of biology too, I would definately recommend looking at CAS assuming it won't cost a lot (if at all) more.</p>
