hahaha...the thought of the PE exam cracks me up. I just took the FE or EIT (whatever you want to call it, the first exam before you can take the PE exam) this past april and that was a joke!
I'm a computer engineering grad so there were like 10 questions on computer stuff, a few electrical and the rest is ME/CivE stuff (of course those disciplines actually benefit from becoming a PE)
Needless to say I guessed on pretty much the whole test and passed. Finished the 8 hour test in about 3 hours. Good luck with your PE exam
