Second choice major

<p>so i got my alternate major (undeclared bio sci) and i’m planning to enroll at UCSD. So what exactly do i do with that? can i/do i have to declare a major when i enroll? my parents are worried about all the “good majors” being taken up since i’m undeclared.</p>

<p>does nobody know?</p>

<p>i'm in the same situation too. i got into revelle undeclared bio sci. anyone got more info?</p>
