The D paper treats the subject in a rudimentary way, or is seriously confused. When organization is present, it is not effective. There may be serious and frequent errors in sentence structure, usage and mechanics, giving the impression of distinctly poor writing, or having been conceived and written in haste. This score applies to a paper that is completely off track or has few redeeming qualities. It often lacks discernable organization.
Mechanical errors can be frequent and a substantial part of the required work is missing.
