<p>Undergrad admissions at MIT are unified - all candidates are selected regardless of intended major. MIT freshmen have the option of choosing any undergraduate major they would like. So no, it is not 'easier' to get into MIT undergrad through the Sloan School than through any other program. Otherwise, every undergrad candidate would just apply through the Sloan School.</p>
<p>More for graduate studies....eh.... I'd say its undergraduate is definitely top notch. US News ranked it second after Wharton for undergraduate business schools (not that rankings matter).</p>
<p>It is easier in a sense. Here's why. MIT wants to see passion in whatever you want to pursue. So if your passion is in business, you can gain many achievements with business, and it'll show how much you love it. However, when you want to be an engineer or a math person, well all the people who apply to MIT are crazy good at that, thus your achievements are diminished.</p>
<p>Basically, being good with business/politiscnece is easier than being good at math, and thats why it may be 'easier' to get in with a different major.</p>
