Essay 3 (what's in your pretty little head) is like Essay 1 - they are BOTH argumentative essays. The synthesis essay requires you to use their sources as support while Essay 3 expects you to come up with your own concrete details for support.
1. Beautifully written intro - take your time to develop "art."
2. Create your own evidence
a. Your experience
b. Your observations
c. Your READING - Into the Wild, Romeo and Juliet, Julius Caesar, A Separate Peace, The Great Gatsby, etc.
3. Well written
4. Use your own rhetorical devices (similies, allusions, metaphors, etc.)
5. Nice conclusion.
