'college application part' is the definition.

This is the entire clue.
(Other definitions for essay that I've seen before include "Analytic or interpretive literary composition (5_" , "Make an effort or attempt" , "Have a shot at a written piece" , "Written composition" , "Attempt - piece of writing" .)
