An A paper will thus stress analysis rather than mere recitation of facts, and it will demonstrate some originality in interpretation. An A paper, furthermore, will also explain cogently the economic and historical significance of the problem under analysis in a broader context. With such qualities, even a paper with some factual errors may receive an A grade. The grade is a reflection of high entrance standards, and not of my own generosity. B grades may indicate that the answer is basically well organized and presented, reasonably correct and complete, but still lacking the analytic skills and originality that immediately stand out in an A paper.
Most B papers are thus much more narrative and descriptive than truly analytical.
I myself committed several of these faults when I was a university student. In the following list, I have checked off those that may apply to your paper, either wholly or, more usually, just in part. It suffers from too many logical lapses, too many non sequiturs . It contains serious errors in historical analysis, confusing cause and effect relationships. It is, on balance, more narrative or descriptive than truly analytical, as explained above.
