When you write your paper, do you think about how it will be evaluated by your professor? Most professors have grading criteria in mind before you turn in your work; if you keep their criteria in mind when you create your paper, you will get a better grade. Many professors use a "grading matrix"; the grading matrix can actually help YOU write a better paper - so if your professor gives you a grading matrix, or hands you "grading criteria" use it to your advantage; they are trying to help you write better.
If you want an A on a paper, keep these things in mind:
RULE 1!! You must know what your professor expects from you.
Rule 2: Your professor is not usually asking you to summarize your readings. Words such as "show how" and "explain" and "illustrate" do not ask you to summarize a reading.
RULE 3: Details Matter. See below.
