I got As in my pre-college math courses but I don't think I breezed through them. My schooling had no separate trig course, it went algebra, geometry, intermediate algebra, and calculus. Various pre- or honors versions. Since the BC exam covers quite a bit more material than the AB, my school teacher required those interested in it to take pre-calculus Honors first which was mostly about shoring up any gaps in previous studies while getting a foothold on Calculus AB material near the end. I think that extra prep made a huge difference in my performance, along with the teacher himself and an insistence on memorizing a lot of things to not be dependent on a rule sheet and getting an intuition for solving problems that even the TI-89 wouldn't help much with.
