I call it "The Great Switch". The idea behind this is for people who are having problems with their major or with their roommates can switch for 2 weeks, so they can really see what it's like outside their little bubble.
People who have declared a major, but are unsure if they've made the right decision can sign up for another major's classes for 2 weeks. For example, maybe a music major is thinking twice about her decision, and wants to explore in psychology because she thinks it'd be a lot easier. She could take all psychology classes for 2 weeks, and see what she thinks.
The same with someone who is having problems their roommate. They might think their roommate is a pain and would like to live with someone else, so for two weeks, they move in with another person.
Two things could come from this "Great Switch":
1) The person could realize that what they have now really isn't all that bad and come away from the experience with a new found appreciation for their life
2) Decide that the life they chose for the Switch is actually a life they prefer, and they could find a new major or roommate.
I often here my CA tell us that everyone likes to complain, but never likes to do anything about it. The Great Switch would take away just a few more things for people to complain about.
I feel like something like this would allow students to explore their options around campus a lot more than just being undeclared or trying different classes from semester to semester.
The biggest benefit I could see coming out of this is music students can explore other options, so they don't feel trapped inside the music program. It'd be an easier way of weaving people out than to pile work on them. It also may help someone come up with a creative major, like music and studio art.
Exploration of your options is a key part of college, and I feel that a Great Switch would make that exploration just a little easier.
