How to get ready for track prelims and final meet?

Damn, tommowerr, Well this is my 2nd year of track i also run 800 with 2:06 and 400 with 53 secs, but what i would do for the 800 I would sprint around the corners and when you come to the straight aways, stride it until you get to the next corner and sprint it agian, after you reach the peak of your corner, just run the last 400 meters of the 800 , your 2nd lap should be as good as the 1st lap. For the 400, sprint the first 200, but don't go all out, when you get to the last 200, just burst out sprinting and don't try to think about the finish line just keep going. For the 100, can't help with that, I'm not a sprinter. Good luck, I have faith in you too.
