<p>Under your circumstances, I would SIR to both schools. Just be sure to drop out ASAP when you know for sure where you're going. Remember, only one transcript will be sent to the school of your choice, so if they don't receive your transcript, the latter school will rescind you anyways.</p>
<p>Yes, i've heard of people getting rescinded from Cal because they dropped below a 3.0. Just work hard, you're almost done(only a month or so left)! Yea, I would submit my SIR to more than just Cal if I were you.</p>
