Duplicate Content and Adsense approval.

So I have a couple of new sites that all use WP and CC for the content. My question is, since my site is very new, within the last 2 days, what are my chances of getting approved by adsense, when all my content is dupe? Does adsense look at that type of thing when verifying your site? Also, is it a good idea to try to adsense your site so early in the game, or should I wait a couple of months to get more traffic flowing in before I try to sign up? This will be my first adsense account, so I hear they are a lot stricter when reviewing your prospective site.
