<p>would they rescind my acceptance(s)?</p>
<p>You mean you switched HS? Your Uc application is complete, yes? Then it shouldn't have any effect if you don't let your grades slip. I see no harm in telling then you have moved. Things like that happen. If your grades slip[ usually a lot] then they could rescind your acceptance.</p>
<p>there's np if you switched schools..unless you're now not involved in anythign/grades are slipping and you were 'excellent' before..</p>
<p>I just found this on the website:</p>
<p>If You Move/Change Schools</p>
<p>If you move or change schools after you submit your application, you must notify in writing the Admissions Offices at the campuses to which you applied. Provide the institution’s name and describe the courses you are taking and plan to take.</p>
<p>So now you know. Just keep your grades up and moving will end up being a non-issue.</p>
