Aggie Grammar Guide

The Writing Support Center at the Academic Assistance and Tutoring Centers presents the Aggie Grammar Guide (AGG), which utilizes authentic UC Davis student writing in order to accurately represent the student work Writing Specialists regularly encounter. The student examples exemplify areas in which students both struggle and succeed when employing particular grammar concepts. In addition, we’ve included style sections as grammar and style are interconnected. Please note, we based the AGG on Standard American English (academic English), yet we acknowledge many other varieties of English exist that we don’t address. Our goal throughout is to provide assistance when grammar becomes distracting—when the sentence construction distracts readers from the ideas, we suggest revision.

Using the AGG:

The AGG is meant to be a reference guide, but please feel free to use it any way you find helpful. In order to access grammar and style concepts, click on the links to the right. Once there, read the concept’s lesson and then you may click on the practice link in the right menu, which will offer  intermediate and advanced practice exercises. These exercises are meant to be printed out and completed by hand before reviewing the answers, which you can access by clicking the answer key link in the right menu as well.
