I studied mathematics as an undergraduate and am now pursuing advanced study in computer science. The foundation that studying advanced mathematics provided me for further study in CS is rock solid, particularly since my interests lie in artificial intelligence realms of CS. I've also found that in "the working world", once you prove you can code, you are a favored candidate for more interesting, complex job assignments by your employer.
Having gone through most of my K-12 schooling in SF Bay Area, I can't say I'm surprised by this decision. Being an advanced student was not encouraged by the school district, nor the schools that I attended. Accelerated programs were canceled right and left to make everything "more fair". Scheduling was always a nightmare. Talking to my husband who went through his K-12 in the Dallas-Fort Worth area was very eye-opening as it seems his district made every effort to push the advanced students forward that much more. At this point I don't consider myself disadvantaged; I was lucky enough to have parents who pushed me to excel in spite of a system that holds people back, but not all are that fortunate.
