The fortunate thing for most of us is that style is simple, it is learnable, and for the effort involved in mastering it, it is cheap. Good written style can turn a D paper into a B minus, time and time again. Style, simply put, separates the acceptable from the unacceptable. It is natural to think that a topic should be interesting to the student, but a word of caution is in order. The same might be said of Ideas.
Ideas are the sure road to confusion, and confusion is anathema to the professorial mind.
You write the paper which is in the teacher' s mind. Your ideas are his ideas, your prejudices are his prejudices, your outlook is his outlook. In this way you achieve the congruence between your paper and the teacher's perusal of that paper, which will denote intelligence to him and a hence good grade for you. Organization is the supreme virtue, not for any abstruse reason, but because professors are usually very careless readers, and easily become inpatient. They must not be allowed to miss your points.
