<p>I am in a very odd situation. I love math and have taught myself (authors in parentheses):
real analysis in one (Rudin) and several (Spivak) variables;
linear (Shilov) and abstract algebra (Artin);
complex analysis (Ahlfors);
topology (Gamelin/Greene);
and a little bit of number theory (Niven/Zuckerman).
[Not just reading of course. I can do the problems, too.]</p>
<p>Here's the issue. I just took the AMC 12 and got a horrible score (not nearly good enough to qualify for the AIME). I am very confused about all this. Does this mean that I've been "fooling myself" somehow about learning math? How is it that I do fine with more advanced subjects but can't even get an average score on something as concrete as the AMC?</p>
<p>Note: I hadn't prepared for the AMC beforehand. It was a last-minute request made by our math department chair. But isn't the AMC more indicative of innate creativity and problem-solving ability anyway?</p>
