How can I keep myself updated with today's current events?

I am a freshman and I am entering a current event competiton. My question is how can I keep ahead of the competition? I listen to NPR and the BBC but I am wondering if they are more resources to keep updated with current events. I really need a good un-biased network that is very up-to-date with everything. Does anyone have any recommendations or tips on how to stay well-informed with all the current events?
