<p>If you don’t even compete but are in the academic decathlon, it’s pretty lame. It’s also unethical (but people probably do it anyway) to say that you compete in the academic decathlon when you are merely in the class.</p>
<p>If you genuinely enjoy it, you’ll probably do well in it. 5.0 weighted is good, it couldn’t possibly be heavily offset by a B or something in the class.</p>
