Help In ISFAA!!- an international student

<p>I'm filling out the ISFAA for Vanderbilt University. I have no clue how to respond to Section F - Expected Support for Educational Expenses. </p>

<ol>
<li>Enter the expected amount of annual support toward your educational costs from the sources listed. (for all 4 years of undergrad)</li>
</ol>

<p>I am unsure about whether I will get a summer job or not during my studies in US, so what should I write in my expected vacation earning columns?? I am afraid that if I leave it blank this may not affect my chances of getting in as my family contribution is also very less. </p>

<p>Thank you</p>
