filling out forms

<p>Hey! This might seem like a silly question but how do you fill out the financial aid application pdf's? I'm an international student so I need to fill out the CSS International Student Financial Aid Application. Williams led me to this link: <a href="http://www.williams.edu/admin/finaid/forms/0910_international_app.pdf%5B/url%5D"&gt;http://www.williams.edu/admin/finaid/forms/0910_international_app.pdf&lt;/a>. But I'm confused because I'm not sure if I need to fill it out by hand because I can't seem to edit the pdf file. Please help!</p>
