<p>I applied to UC's but my alternate major was bio, did i mess myself up? I am a low mediocre candidate so I am afraid I screwed up</p>
<p>At all the UCs I know about, your intended major is not taken into account when you apply for a major that is in the College of Letters and Science (unless your 1st choice was Computer Science). You should have read this on the FAQ or evaluation pages for the admission offices at the UCs you are applying to. So if both your 1st and alternate major are in L&S then listing the alternate major was meaningless. If your 1st major was in a different college then it varies by campus whether they’ll even consider you for an alternate major. If they do, again it falls under the rubric of L&S admission in general and not your specific major in L&S.</p>
<p>This assumes, BTW, that you are applying as a frosh applicant.</p>
