<p>Would it be bad to allude to my main Common App essay in my supplement essay?</p>
<p>In my supplement essay I make a passing reference to something that wouldn't make sense if you didn't read the main Common App essay first.</p>
<p>There is no way to know which essay will be read first, or even if a particular reader will read both essays. On a second or third read someone might just read one.</p>
