The University of California is releasing admission decisions this month and many students are finding themselves waitlisted. The UC states: "Whether or not a campus will offer admission to students on a waitlist depends on a number of factors, including the number of students initially offered admission who accept a space by the Statement of Intent to Register (SIR) deadline (May 1 for freshman, June 1 for transfers), and campus and department enrollment goals. There is nothing that a student should or can do other than opt-in to the waitlist by the stated deadline. Any additional information submitted that was not requested by the campus will not be considered.
The process for selecting students from the waitlist varies at each campus. A campus might have enrollment goals for a particular major, leading to the admission of students who applied to that program, but not others. Or a campus might admit broadly."
Students can remain on more than one waitlist and it is a good idea to do so.
