<p>If a college asks me to write a letter to my future roommate, which they will then read, should it be informal? Or should I take it as just another essay? Because I can be very funny when writing informally, but if I treat it as another essay it doesn't have the same feel. what should I do?</p>
<p>It'd be best to write informally. I think that, as a general rule for all (or most) college applications, you should use your own voice.</p>
<p>yeah, i would also say to write informally. you should still use correct grammar, of course, but let your personality show through the essay.</p>
