<p>That's a misconception about Chicago and Reed. They do indeed relax. There's the supposedly "nerdy" atmosphere, but those who don't like the schools, more so Chicago than Reed, constantly jab at them by saying they don't know how to have fun. They do. They also work hard, which you'll be doing at any top university.</p>
<p>Now, regarding the colleges on your list, just from general perception (though I have no way to back any of this up, and some of it is probably wrong):</p>
<p>Dartmouth is an intellectual but laid-back school that you can relax in, but you will have to work, as at any school.</p>
<p>Brown is very much the same.</p>
<p>At Tufts and URochester, you'll work to get your degree, but there's plenty of relaxation and "college life" things. They seem rather neutral to me.</p>
<p>I'm not sure about the others.</p>
<p>Remember that your major is very important to how hard you have to work. MIT is known for being very rigorous (going to MIT is like "drinking from a firehose," I've heard), in large part because engineering/hard sciences are among of the most difficult majors, even for the smartest students.</p>
<p>I think neuroscience would be rigorous, but not as difficult as, say, electrical engineering. It's definitely not a "fluff" major. Remember, also, that neuroscience isn't a common major -- more of a grad program. If it is an undergrad major, it's often a very interdisciplinary one. (This is just my perception -- I'm not completely sure about all of the colleges you list.)</p>
