If Plan A doesn't work?

It's official. I've submitted my applications for grad school. I've applied to a couple of graduate programmes in the UK for transportation planning and management. Actually, I submitted them a while ago, but have been too afraid to talk about it. Cuz now I'm stuck that waiting period. Do they like me? Do they think I'm a complete joke? Will they let me in to the country? Will they let me into the school? If they don't, what will I do then?
