<p>This is what my understanding is: Student is allowed to enroll in 9th semester only if unit ceiling of 130, for someone who has declared one major, is not exceeded. If student’s accumulated unit count is 130 or less, student is allowed to enroll in 9th semester regardless of how many units the student take in 9th semester. </p>
<p>Please also note the following:</p>
<ul>
<li>Unit ceiling for the students with 2 declared majors is 136.</li>
<li>Only fall and spring semesters are counted and summer semesters are not counted.</li>
<li>Transfer students with one major is allowed 4 semesters and students with 2 declared majors are allowed 5 semesters.</li>
<li>Only units earned at Cal are counted towards unit maximum ceiling and not any AP, or community college course credits student may have transferred.</li>
</ul>
<p>There is an appeal process in place to request permission to extend enrollment beyond these limits. It is said that those permissions are rarely granted and only under extremely unusual circumstances.</p>
<p>Hope this helps.</p>
