<p>I submitted my application with my main major as comp eng. and my alternate as comp sci. I’ve been having second thoughts with the comp eng, so if I do get accepted on the comp eng, is it possible to immediately change over to comp sci or should I try telling the admissions office right now?</p>
<p>your best bet is to send a letter or call now, but if it doesn't happen you can only transfer if and when you get in.</p>
