<p>Just another data point – one of my kids had a rough time with math in high school, culminating in a D in pre-calc in his junior year. He retook it the following year and got an A. Since then he just finished his freshman year of college as an engineering major, and got an A in Calc 1 and 2 (in fact he’s pulled a 4.0 overall in his final year of high school and first year of college). He attributes the change to two factors. First, he thinks he had poor teachers early on, or at least ones he didn’t click with. Second, he found calculus not at all as daunting as he was expecting; rather, he’s enjoyed the kinds of problems involved compared with prior math subjects. So regardless of when you end up taking calc, don’t rule out the possibility that you could really take to it in a good way.</p>
