<p>I’m assuming you were admitted as a freshman? Here us what it says on the UC page;</p>
<p>"All incoming California students who have not met the Entry Level Writing Requirement by April 1, must take the UC Analytical Writing Placement Examination. The exam will be administered the morning of the second Saturday in May, at testing centers throughout the state.</p>
<p>In early April, students will receive a letter directing them to the test center at which they must take the test.</p>
<p>In mid-June, students can log in to their campus’s admission website to check whether or not they have passed the exam. Results of the exam will not affect a student’s admission to the University. Those who do not pass the examination can still satisfy the Entry Level Writing Requirement before enrolling in the university by achieving a satisfactory score on one of the tests listed above or by completing an acceptable college course in English composition with a grade of C or better.</p>
<p>Students who have not satisfied the Entry Level Writing Requirement at the time they enroll in their classes must take a writing course designated by their campus."</p>
