From what I read in other forums, it seems like a toss up between Chemical and Electrical Engineering though leaning toward Electrical Engineering. Personally I used to think Nuclear Engineering was the toughest and I still don't know why it isn't.

I am looking for a kind of grid paper--either bought or printed out, that has lines down the side and then vertically (usually slanted) across the top. It would be like the material you find in an atlas, with cities down one side and across the top, with the distances listed in the spaces. I think I could jury rig something, but does anyone know a simpler way?
