<p>First of all, you would have to apply for readmission to the university if you wish to resume you studies here, see this page: <a href=“http://registrar.berkeley.edu/readmission.html”>http://registrar.berkeley.edu/readmission.html</a></p>
<p>For your second question, I believe you can, but you would be applying as a transfer student with more than the usual amount of credits. You should see an adviser about this question.</p>
