The Grammar Essentials area of the Excelsior OWL will provide you with a thorough overview of punctuation, grammar and usage, and some of the most common errors students in the United States struggle with. And, by using a little humor, we hope that this introduction into grammar and punctuation (using zombies, memes, and funny stories) will be a little less painful than when you were in junior high and had to do things like memorize prepositions or diagram sentences.
