<p>ISP is a separate application process that you complete once you get accepted into NU. Here’s more info: <a href=“http://www.isp.northwestern.edu/admissions/applying.html”>http://www.isp.northwestern.edu/admissions/applying.html</a> . Your common app major really doesn’t matter, just what school you apply to as most people don’t declare an official major until your a sophomore. Good luck applying!</p>
