Son of a bitch.. I have many papers ahead of me. That sounds like a PhD thesis sized paper though, hope I never have to right than for a bachelor's
i'm an undergrad. well, was undergrad shall i say?

this was the last paper i had to write. only 4 finals left now, then i am done! :Q
PhD sized? Not quite. Think a couple hundred once all is said and done. I remember for my bachelor's I had to write several papers of that size or larger. Biggest topped in a 118 pages. But seriously, congrats on finishing your paper man. Good on ya.
118 pages in undergrad? please tell me this included charts/graphs, etc. cause if not, that's crazy :Q
Congrats. Those ~40 page papers are the worst. I had several of them (physical chemistry lab had several of them, and chemical engineering lab). It just takes so much out of you and every page has to be good. But when you go to larger papers that are only skimmed (MS thesis or PhD dissertation) there is a lot more room for non-essential stuff. Thus you can really ease up on the editing on the bigger papers and that is a lot easier to do. Just type until you have typed everything you have to say and the thesis and dissertation will be done.
For reference to other posts: the typical MS thesis is ~100 pages and the typical PhD disseration is 200-250 pages. There is a huge variety as I've seen some that are just a few pages and some which are ~1000 pages.
I know, that's the hardest... you cannot maintain the same level of concentration through out the paper... i spent 6 hours on thursday, 6 on friday, 8 on saturday and 7 hours on sunday... crazy...
41 pages of dense material? or 41 pages double spaced with charts and graphs?
only 3 pages of charts and stuff...
