Is 203 a good PSAT score? Could I make National Merit Scholar?

I don't know much about the PSAT of SAT. Right now I'm a sopre and made a 203 on the practice PSAT this October. I've heard National Merit Scholar is really good for getting accepted to a college. Is 203 good? What score would I need? Do you think I could make National Merit Scholar? What actions should I take to get there? Thanks!
