For example, here is a sample of the writing produced by my TA:
If you are citing from the same book several times on one page, do not write full reference every time; rather it use "ibid" sign.
Do a proof-reading before submitting the paper. It is not a bad idea to ask someone to read it after you so that he/she may provide a basic feedback for it. Unfortunately, there were sentences and paragraphs I could not really understand to - though I did my best. This may improve your paper significantly then...
So what I wonder is this: Did she not understand the writing because the writing was bad? Or because she doesn't understand good writing?
