<p>I know USC and U of Miami are both really hard to get into, and they're definitely reach schools. What are my chances of getting in and what can I do to improve my chances? Also, is it realistic to consider UC Irvine and UC Santa Barbara as safety schools? Thanks so much!</p>

<p>USC: reach
UMiami: high match</p>
