<p>I don’t think grades measure intelligence, at least not my opinion of what intelligence is.</p>
<p>I know lots of people who got excellent grades but are dumb as bar stools.</p>
<p>I’m not sure why posters keep using the term “obedience”, sounds stupid. I mean, if you want to learn a subject you’ll need to put time into it, that should be obvious.</p>
<p>Aptitude and intelligence are separate things in my book, and grades generally measure aptitude for a subject pretty well.</p>
