Presidential Fitness Testing... Mile run?

Hi.That is what happened to me back in high school and jr. high.I would usually always be the last one to come in. Sometimes I would have a buddy that would go along side with me. Anyways to get better, you may want to practice running on your own time. Just try to walk and run. Build up your strength and endurance. Otherwise aside from that see if your instructor would allow you to listen to some music while running. That really makes running easier.
