The maximum character count in the given box is 7900, but you are allowed to upload a document (which doesn't have a specified length). My essay is 2,213 characters long--is it too short?

Undergraduate / UPENN page 217 of a 300 page biography [4]

This is the optional essay for UPenn: You have just completed your 300-page autobiography. Please submit page 217.

Am I allowed to submit page 217 of my 300-page autobiography as of right now, or is it a 300-page autobiography of my entire life? In other words, am I supposed to be writing about the past or the future?
