<p>Yes, in my personal opinion, which I wish to make clear is absolutely unofficial in any way.</p>
<p>Are you an international by any chance? That is an entirely appropriate response if applying to a wide variety of international schools. For example, if applying to Cambridge, using your personal statement to discuss anything other than the glories of your intended field of study and your passion for it is a mistake. However at Cambridge, you are admitted to (say) the physics department. Whereas at MIT, you are admitted to the university.</p>
<p>One of the reasons that intended major has so little impact on MIT admissions is that nobody knows what they want to major in. Nobody chooses to major in Nuclear Engineering due to that great experience they had with their high school reactor. Indeed most fields of study offered at the university do not exist in high school. Even fields like Economics, Meteorology, and Archaeology which people have some idea about, probably were not taught in Secondary school. Even for those who do come in with a clear idea, say for example that they have a real love of chemistry. OK, then do they want to major in Chemistry, in Chemical Engineering, or in Materials Science, all of which rely hugely on chemistry, or do they want to do biochemistry? Do they even know the difference?</p>
<p>A straight majority of MIT students change their intended major, and speaking ONLY about your love for a particular subject is often misguided. MIT is looking to admit real people. If the only thing that comes off of an application is that you like and do well in physics then that, in my personal, unofficial opinion, does not enhance your application in any way.</p>
<p>If MIT asks what you do for fun, bringing in physics is vaguely strange (barring your being a Yo-Yo champion or some other such thing), if MIT asks “Tell us about your background and how that affected who you are” then bringing in Physics is again a tad unusual.</p>
<p>From the MIT website. The essays “are the places in the application where we look for your voice - who you are, what drives you, what’s important to you, what makes you tick. Be honest, be open, be real - this is your opportunity to connect with us.”</p>
<p>Don’t think for a moment that they are lying about that.</p>
