<p>An upper division student (transfer or “native”) can take lower division courses.</p>
<p>Of course, your major may require a specific number of upper division courses or units.</p>
<p>Also, [Berkeley’s</a> College of Letters and Science](<a href=“http://ls-advise.berkeley.edu/requirement/summary.html]Berkeley’s”>http://ls-advise.berkeley.edu/requirement/summary.html) requires you to complete at least 36 upper division units, including at least 6 outside of your major department. The 36 upper division units is only 60% of the 60 units you would typically take over four semesters.</p>
