Here are a couple materials for you to assist you in your studying.
First, a summary of Chapter 11, Sound and Sense, regarding musical devices. You know many of these terms, but a bit of review would probably help.
Second, this link presents the three types of timed essays you will do on the test: the poetry essay (essay 1), the prose essay (essay 2), and the open-ended essay (essay 3). Go to this link. Scan downward until you reach the sample essays and responses. They are listed by year. Looking at these and studying them should give you further insight into the task of writing the essays. Very good resource.
Third, some advice on preparation. For the terms on poetry, just go over them several times. Don’t go crazy memorizing. Just have them in the forefront of your mind, as they can come in very handy on the objective portion of the test. The biggies for writing are the ones we keep talking about in class: irony, imagery, metaphor, simile, personification, paradox, oxymoron, tone, mood, symbol, descriptive detail, connotation, apostrophe.
As for the open-ended essay, I would choose 2, maybe 3, of the major works we have read, and re-familiarize myself with the characters, action, themes, so I could write about them in some detail. I want to know the work well, so I can use supporting details to back up my claim in relation to a broad prompt. Looking at those past year’s prompts and the student responses should give you a good idea of how to review. Sparknotes and the like can prove useful for review, as well.
