<p>I want to study math-cs, maybe econ, don't care much about sports/party. Please help me.</p>
<p>many people warned me that after you came to US you'll chang your mind and study econ. Is it true? Thanks.</p>
<p>i haven't heard specifically about switching from math or computer science to econ after coming to the US, but it's pretty widely accepted that many people (or even the majority) tend to change their minds about what field they want to study in college several times.</p>
<p>Don't think that because williams doesn't have a frat presence that they don't have a heary sports/party scene because they have both. I think you need to visit both places, compre the cirrculums and find out which one is best for you.</p>
