The most pointless weed-out class at Purdue University. Every engineering student is required to take it and no actual knowledge is gained. The purpose of the class is to confuse the shit out of everyone and make us do about 20 hours of homework every week.

Oh... and did I mention it's only a 2 credit hour class?!
Dude, why are you falling asleep? its only noon!

I was up till 5 a.m. doing my ENGR 131 homework last night. Just like every other week this semester.

The first year engineering class you take at Purdue where no one knows what they are doing (not even the teacher's assistants or professors most of the time). The class goes all the way through the semester like this and everyone gets A's.
Freshman asks sophomore: "What did you do in ENGR 131?"

Sophomore: "Nobody knew, but we still all got A's.
