<p>My son goes to a small school. There are 75 or so in his class. He’s a junior. He and 14 others are in Calculus.</p>
<p>When I was in school, it was more like you described. Pre-Calc was the typical senior class. A small group made it to Calc as seniors. There were never juniors in Calc.</p>
<p>I think tracking for “talented and gifted” programs has identified more people that, in a supportive environment, can be accelerated in math. In fact, I know several kids who are taking Calc as Sophomores. They are no smarter than th rest. They just attended a tiny, rural public school that had a teacher that made math fun and was given the freedom to go at the pace the whole group could handle.</p>
