<p>To all the current columbia Students, how hard are the science courses there, particulary the 2 semesters of general chemistry and the two semesters of organic chemistry? The only reason I am asking is because I was think about doing a concentration in biology in addition to a major and I wasnt sure if it was possible?</p>
<p>Chem is probably considered one of the hardest sciences at Columbia.
Organic Chem (Orgo) is even harder. People generally take these classes only if they're premed.</p>
