TAG to UC Davis

When I filled the tag application and UC applications I thought that I would get into a physics class but the class filled up before I could register. I will definitely meet the credit and GPA requirements and have enrolled in a computer science course to fill the void of physics. My TAG application did get accepted, but I’m worried that if I cant find a way to get into this physics class then my TAG will be revoked. Any ideas on whether small schedule changes will make my TAG application get revoked?

Also my major: College of Letters and Science: Computer Science

You can settle for guesses here about with the admissions office at Davis might do. Or you can ask Davis directly, with the bonus that if the change does matter there may still be time to work something out with them in order to keep your TAG.
