Senior thesis writers should take revising and editing of their research papers as the most important step in their research. Every body can write a research paper. But what makes your paper senior, or distinguishable from those of others are the errors that you notice. The purpose of revision is to look again into what you have written. Be opposed to and alien to your work. Hand a draft for appraisal by another student before the final submission. Edit to get rid of superfluous words, to reorganize words into stronger and clearer meaning and for perfect transition and connection of thoughts. If you want honors, never leave these out.
