Stanford's EPGY Deadlines

<p>What are they for mathematics? On the site, it says 22nd of the previous month, but it is not expressed clearly. Since each course starts every month, what exactly are the dates? </p>

<p>Also, how hard is the EPGY Mathematical Aptitude test (age 13 only -_-) ?</p>

<p>No answer?</p>

<p>From your information I'd assume if you were taking the course in March you'd have to apply by Feb. 22...</p>
