<p>I disagree with your guess. Proficiecy in all major subject areas require long term dedication. In math, for example, a “good” math HS student would have to spend four years to reach the level of elementary calculus. In biology, you can move from HS bio to advanced stem cell research in just as many years if not more. In music, it may take a kid 8 or more years just to be able to play interesting piece by sight. A demonstrated proficiency or expertise in any major field of study IS an indication of ability and discipline for sustained learning. It is definitely not unique for FL.</p>
