I'm conflicted on this. Having moved 18-20 times across 7 states before high school, I'm intimately familiar with the inconsistencies between curriculums that existed before common core. I was taught some things 3-4 times while others I missed entirely. I also, through a series of (in hindsight) unfortunate events, ended up at the point of taking calculus my freshman year of high school and had three years of no math before college. While it was convenient as a high schooler, it really bit me when I started college and dropped straight into advanced calculus after a three year hiatus of all things math. Harmonizing with the common core is fantastic. But school districts should also strive to harmonize with surrounding districts when it comes to "extras" like this, as well.
