During my degree, trying to work with others was a huge pain in the butt. Every bit of work was a nightmare. I ended up doing it all anyway, simply because I refused to put my name to some of the rubbish I was handed by other participants - when they could be bothered to contribute anything at all. Channel your inner control freak - you might just be the lucky one. You're assuming that two people would've have researched/written 2500 words each and you would've had half the work you now face. In my experience, this simply wasn't the case.
