can someone please explain how the core works

<p>I’m not sure you really want to to be pre-med at Columbia. In your second year, you will have a class with this woman :[CULPA</a> - Deborah Mowshowitz](<a href=“http://www.culpa.info/professors/2673]CULPA”>http://www.culpa.info/professors/2673)
You will always be stressed. Class averages in chemistry courses tend to be about 60-65. Even more, you will not actually get to take any of the science classes you want until the end of 2nd year, maybe. Oh, and your AP Bio credit: doesn’t count. Your AP chem credit might count if you pass a placement test in the first week. Be warned, college chemistry and biology are nothing like high school chemistry and biology.
I might change my mind, as I am still a freshman. Who knows, as a senior I may start crying when I leave campus. But, from what I’ve seen here Columbia is insane. I advise you to go to Yale, it’s low stress, a nice quiet environment, a small college and there are no issues with housing. Don’t get me started on housing!</p>
