All that you've been studying is fair game for the test but below is a comprehensive list.
Study the importance of each major place (if we discussed it) - i.e. Vicksburg - the last major stronghold on the Mississippi and if the Union took it it would cut the Confederacy in half AND Cumberland and TN Rivers - control of the rivers would cut TN in two and provide the Union with a river route deep into the heard of the confederacy.
