question about registration block

Colleges and Universities A-Z University of California - Berkeley

<p>today i am trying to add class, but telebear shows me that my registration is blocked by the office
I searched on google, and i think the reason maybe is I did not declare major.
the reason why I did not declare major is that I need one more lower-division to take in summer.
I emailed to my adviser last month ,and she told me I can declare major after I take that class.
but the question is if I don't declare major right now I can't add class in fall right now
can any one give me some advise??</p>

<p>my friend told me I can declare another major first to clear the block ,and then change major.
but I am worried that if I can change major after I declared one.</p>

<p>No problem changing majors - doesn’t matter, when you show up with the signed form from your new major showing you are now permitted to declare, your college will process it without caring whether you had a different major before.</p>
