Having finished high school, a little over a year ago, I cannot understand how this can be beneficial in any way. We began pre-algebra in 6th grade and a large majority of kids did Algebra I 7th grade, possibly a harder class like Geometry, depending on how ahead they are. Sure, you could delve deeper into each topic, but when your classmates, are still struggling with basic Algebra, how much time does your teacher have to focus on giving you extra work? The accelerated kids would essentially be forcibly held back. The curriculum at my high school for the normal accelerated student was Algebra II, Trig/Calc A (calc I), calc BC (calc II), then calc III, and we had students even more accelerated than this. Starting at Algebra I in high school, would essentially shift everything back two years.
