Grammar and Punctuation

Both grammar and punctuation are extremely important in writing. Depending on the teacher and the course, a writing assignment rubric could put a significant amount of weight on these combined areas (sometimes up to 30% of a grade). Whether you're an outstanding writer or a struggling writer, we hope that the information provided will help you to further improve your knowledge of written English.
