<p>Competition math isn’t directly correlated with college math. An extremely strong math competition scorer is unlikely, if basically interested in college math, to be bad at it, I’d guess. Creativity in problem-solving, and strong skills of observation, seem to help a lot in acing difficult competitions, and these will also help in college math.</p>
<p>What’s crucially different about college math is, as with any major, you’re charged with the task of <em>learning</em> a lot. If you’re not interested in absorbing the details of what you’re learning carefully, you won’t perform as well at it. This is the main reason I’ve seen people with high mathematical talent not really do that exceptionally well in college math. </p>
<p>A person’s ability is one thing, but the complexity of the subject is quite another – it needs to be broken down steadily and digested, which takes effort and interest along with aptitude. </p>
<p>If you can read and write proofs when you come in, you’re pretty well-equipped, like people are saying, and if you can’t develop this ability tremendously, at least try to develop it a little. It feels a little less disheartening. </p>
<p>It’s kind of like, one can succeed at an intro CS course at a strong school without ever programming before, but since the course will probably not focus mainly on programming, and they’ll expect you to pick that up quickly, it’s best to not be totally unfamiliar coming in, even if mostly so.</p>
<p>Ah and I thought I’d add - what is “mathematical maturity” … </p>
<p>It can mean different things for different levels. I think a few things to say:</p>
<ul>
<li><p>mathematical reading/writing is different from English. It has its own language, patterns, etc. I tend to write with more English than just pure symbolic writing, and that’s just my taste. However, the barrier in translating stuff to mathematical jargon is tough at the start.
Writing/reading proofs here is mostly what I mean.</p></li>
<li><p>Recognizing the subtleties behind a definition or fact. Why is it surprising? What makes it true? What is at work? Why did they define it this way rather than that way?
Of course to some extent, this goes back to the first point. </p></li>
<li><p>Being able to guess based on how mathematical reasoning is written on paper, what techniques they’re employing, and/or what the approach is. A basic example being how in a basic analysis course, they subtract this from that and that from this, and show some kind of convergence. It’ll be a bunch of formal lines. But there’s something going on there.</p></li>
