There are a number of important terms I think you should be familiar with in poetry, including figures of speech. You will also have the opportunity to write in several different poetic forms, some rigid in their structure and others much more free-form, maybe like a parent or grandparent who is more hippy than stodgy. On the website, you have a form that includes poetry and figures of speech terms. Definitely study it, particularly as we work on specific poetic forms. In the meantime, how about quizzing yourself about what terms you already know?
