The thing is, you are not the originator. You are first reporter, which is a subtle but important difference.
If I were the first person to report the height of Everest, it would not mean I "owned" that fact, or that I should get special treatment because I was first.
That said, the fact you have a "scoop" should mean that you are able to take advantage. You need to concentrate on Freshness indicators. Personally, I would make use of things like Twitter- not just for the SEO benefit, but actually to drive traffic.
Do you have a Social Media strategy? Following your example, you could have your site and Twitter ID published in student-oriented online and offline locations. Drive subscriptions before the event, and then make sure you fulfil your promise of early notification. Tweet the headline, and a URL and encourage retweets.
