A Question About Writing Conferences

This summer, I have the fabulous opportunity to attend my first writer's conference, which is very exciting as well as incredibly anxiety-inducing.

I get to submit 20 pages of a manuscript that I will presumably work on during the afternoon sessions as well as 20 different pages for a one-on-one critique by an instructor.

The deadline to submit the pages is this weekend. My question is about the strategy you experienced conference-goers would recommend for the pages I need to send in. Would you submit pages that need work or the most polished chapters?
