The quarter system does not make pledging easy in the slightest. Especially in the Spring!
Spring rush is normally 2nd week because p/r is during 1st week. So all the new pledge get to know each other activities are 3rd week and you have mid terms 4th week! Sucks beyond all comprehension.

Then you've got all the philanthropies around 5th and 6th week. Like Derby Days and ISVT.

(By the way, I'll be shocked if Mtv doesn't find a way to devote an entire episode to ISVT. Hundreds of sorority girls running around on a beach in bikinis. It's Mtv heaven!) Then throw in days like UCD's Picnic Day and UCSD's SunGod Festival. Your're lucky if you pass any spring classes let alone do well.
