No ambiguity or illogical thought affects the discussion. Sentence structures are varied. Writing is clear and concise, with a consistent point of view, and free from serious grammatical errors, such as fragments and dangling modifiers. Discussion is filled with depth and insight. Paragraphs are supported by specifics but are less developed than paragraphs in the A essay.
Paragraphs still flow smoothly from on to another.
Overall discussions is sound. Sentence structures are sufficiently varied. May contain one or two serious grammatical errors. Minor errors still do not detract from the main points in the discussion. Less depth and insight than the A essay.
