Essays to prep for?

<p>Hi, </p>

<p>I am going to be a senior this coming year so I am writing my essays during the summer.
Which essays should I write?</p>

<p>I have only found the common application ones, but I live in california and I am applying to UCs, CSUs, and other private and public universities and colleges? </p>

<p>Any suggestions for essays that are constantly reused?</p>
