Transferring out is a good point; it'd be much harder to transfer in. People talk about people coming out of MIT having 'inflated salaries', but are there any sites that quantify the value of a MIT degree for the path I hope to pursue (CS)?
So AP BC calculus and calculus based classical mechanics and E&M. The biology and chemistry requirements can be satisfied with sufficiently disparate courses they can't be assumed as base knowledge, there are now five different options for Introductory Biology (http://catalog.mit.edu/mit/undergraduate-education/general-i...) and you can do wet or solid state chemistry.
This is based on IRS earnings data, not surveys. The median salary of a CS grad 3 years after graduation is $163,496, I assume Z is also represented (though if Z is notably less selective than MIT, your place in the salary distribution might also be quite different)
