I'm don't think Serena really wanted to go to Yale in the first place. She only applied during the time when she and Blair were fighting and she wanted to make Blair angry. Now it seems as if she was just trying to make Dan happy. To be honest, I think that she is more of a Brown girl, and would be happier there. As for her and Dan ... I'm not so sure at the moment. The whole joint family storyline is getting very complicated.
