UC transitions from quarters to semesters in 2012.
If you graduate before Fall 2012, you will not be affected by the calendar change. If you begin your studies on the quarter calendar and do not graduate before Fall 2012, you will be affected by the change and will be considered a "semester transition student."
Keep in mind that you are actually quite accustomed to a semester calendar. If you've been to high school, you've gone to school in a semester calendar.
