When do I have to choose a major?

A.B. students normally choose a major officially at the end of their sophomore year, although there is the option of becoming an early concentrator a term earlier. Many students will have decided on a major during their first year, while others continue to weigh possible options up to the last minute. At the beginning of their first term at Princeton, most students have no firm plans about a major and are open to exploring a variety of fields. Many of those who have already made firm decisions will end up changing their minds after being engaged by new fields of study that they had not previously encountered.
