Under no circumstances should you be copying or using the work of others.
It is fine to discuss problems (in general terms) with others, but the specifics of a solution and all of the writing should be done without any collaboration. (See also Academic Conduct)
This policy will be strictly enforced, however if your case does not fall neatly into one of these categories, it will be handled separately, and will possibly be included in a revised version of this policy.
