<p>I applied to Berkeley and some other UCs but just found out that I got into Princeton ED, so I need to withdraw. Despite half an hour browsing their website I have no idea how to do this. Do I simply call them up? Should I send them a formal letter? Anyone know?</p>
<p>I dont have any authority on the issue but calling the admissions office/ sending a letter makes perfect sense. </p>
<p>Congrats on getting into Princeton.</p>
