<p>I know that you can’t take all of the classes that you wanted to, but I wanted to point out that 5.xxx classes are in the Chemistry department, not biology.</p>
<p>7.012 is Intro to Bio, taught in the fall by Professor Langer, who is widely regarded to be awesome.</p>
<p>7.013 and 7.014 are taught in the spring, and they are the bio classes that most freshmen take.</p>
<p>3.091 is taught by Professor Sadoway in the fall, and is considered the easiest chemistry course.</p>
<p>You should check out the seminars online! [MIT</a> Class of 2011: Advising & Exploration-](<a href=“http://mit.edu/firstyear/fas/]MIT”>http://mit.edu/firstyear/fas/) A lot of them sound really cool and it might be slightly more helpful than asking CCers which one you would be interested in :)</p>
