Binghamton University's excuse for a guidance counselor. Students are required to look at a christmas list of classes, that seems to be printed in german, that they are required to fufill. Reading DARS is like trying to understand the immigrant TA's sorry excuse for english at Binghamton. And if something is supposed to be on your DARS that is not on there, good luck fixing it. The schools staff takes a step per hour and runs on the DDS system. (Doesnt Do Shit)
Fuck DARS, they suck ass.
