<p>I was on the UMich site, and it says you must take 115 and 116, and 130 at the same time. But I don't get it, what are 115/116? There can only be one lab, right? And one lec, that that is 130. So, what are 115/116, 2 labs or something?</p>
<p>The general chem lab is 125/126 (I believe they split it to let pre-med students get out of some requirement they have). Chem 130 is just a general lecture class (3 lectures and a discussion per week). Chem 125/126 is one lecture and one lab per week.</p>
