Help! UCSD Bioengineering Major

<p>I was recently admitted to the University of California San Diego, but they put me into my alternate major of "undeclared" as opposed to my desired major of Bioengineering. I don't really want to waste a year of $40,000 tuition to just take general education classes and then extend my college another year. Is there anything I can do to get into my major or am I out of luck?</p>
