<p>I am admitted as an economics major at UC Merced for Fall 2011. I now want to change my major to biology because I have previous biology experience (as well as many of the prereqs already completed). Is it possible for me to change my major to biology and take bio classes for the Fall? If not, will be I able to after a semester or so? I’m not too sure what I can do, and would really appreciate the help. Thanks</p>
