Writing Quality
Here are some things you can do to maximize your chances of
earning a high writing quality grade:
Explain the material in your
own words - your report should be your understanding and
explanation of the material. Avoid generalities, try to
include specific details and examples from the reading
section. The separate sections or paragraphs of your paper
should blend together into one seamless coherent report. Generally
even a one page report should be broken into a few shorter
paragraphs. Your report should be nearly free of
misspelled words and grammatical errors.
