<p>I have a relatively unique EC, and the one I consider to be one of the ones I'm most passionate about. I read math books, occasionally physics books, I program as a hobby, and I self-study APs, as a hobby (I swear!).</p>
<p>What I'm really asking is, how much should I use this on my resume? I know that on one hand, it's obvious that you have to express your passions, on the other hand it seems like this isn't really an EC, it's...schoolwork. </p>
<p>To date I've self-studied Biology, Psychology and Physics B. Maybe I shouldn't use this as much as an EC since it's directly tied in to school?</p>
<p>I've also read "Calculus" by Michael Spivak and "Introduction to Mathematical Analysis" by Rudin. I'm considering getting a head start on multivariable calculus as well. Both of these books were/are quite difficult to go through, and are seen as very rigorous (and normally only read by math majors, a physicist or an engineer taking requisite math courses would use a different text). I plan on majoring in pure math.</p>
<p>I'm also considering majoring in computer science, which brings me to my other passion: I do a bit of programming as a hobby. I'm not particularly stellar at it, I've never progressed anywhere in USACO and I've never really done any other competitions. In terms of math, I've never really made any progress in AMC/AIME/USAMO or other competitions either, I just do it for fun (and the math I do for fun is different than AMC/Art of Problem Solving type stuff, it's a little hard to explain if you don't know what I'm talking about).</p>
<p>The above paragraphs are a bit of a mess, so what it boils down to is, can I use this type of thing as a passion, if it really is one, or will I be viewed as one of those students who just spends all their time studying and not doing ECs? Should I maybe only use the things that don't have associated AP tests as a passion?</p>
<p>Input is appreciated. :)</p>
