Format -- A Note about Postscript Questions: The "P.S." at the end of a letter stands for Postscript. It means that the writer has more to say. We ask you to write a postscript after you finish each paper so that you can tell us more about your experiences writing the paper. This not only helps you to reflect on the process of writing the paper, but it also gives your instructor insight into the challenges and successes you experienced as you wrote your essay. Reading your postscript helps us respond more effectively to your writing.
