Yes I made a football site and ads for the SAT test show up? DO you know why this would happen or will it change? there is a lot of content about football
What's the URL of the site? Hard to say without actually seeing the content... obviously there must be trigger words happening. If it's a subdomain and the Mediabot hasn't visited yet, sometimes AdSense will choose ads based on what's on the main domain, too.
Have you tried pointing out the relevant content to the adsense bot? https://www.google.com/support/adsense/bin/answer.py?answer=23168
