No more than one major error per page, requiring careful proofreading. Overall and in the individual paragraphs, the paper consistently attends to detail with appropriate proportion and emphasis. Ideas are supported with concrete, substantial, and relevant detail. The paper has a limited topic and stays on that topic, but the central topic is not as significant as the A or B paper s. The parts of the paper are connected, so that readers do not encounter gaps in thought or become confused.
Paragraphs are generally coherent with transitional links among sentences and between paragraphs.
There are some errors in sentence form, e.g., fragments, comma splices, or fused sentences. The sentences lack the distinct skill of a superior paper. The paper presents the topic in an orderly way which readers can follow without getting lost. But the order is not always the most logical or readable. Sentences are constructed for clarity but often lack the variety and emphasis of superior papers.
