Student may or may not have done a satisfactory job of responding to writing instructor's comments on mid-process draft. The essay is essentially on the topic, but something is off the mark. Writer misses the point, doesn't quite answer the question. Writer relies excessively on repeating what other sources say, without commenting on those sources' statements. Paragraphs are not coherent, or are not logically related to each other.
Writer presents facts, information, statistics, without sufficiently explaining their significance.
Writer relies too much on one source, and doesn't get much out of that source. Mechanics are faulty. Mustard or pizza sauce are spilled on one or two pages. Student has largely ignored writing instructor's painstakingly thought out and carefully considered comments, written late at night while children sleep secure in the knowledge that their father is providing for them, and while writing instructor is taking seriously the idea that he is serving the Commonwealth. Student has written an essay that is evidently about the assigned topic, but that fails to provide a clear theme.
