The first thing that comes to mind is that if it wasn't for Asians, this country would truly be in a sorry state. What makes Asians more successful in general is a greater dedication by the parents towards their children's education success and ensuring distractions like drugs and sex affect their children as little possible. The second thing that comes to mind is that California has a significantly higher spending per student compared to a state like Texas and definitely more liberal policies with comparable Hispanic population percentage, and yet it is doing worse. You can only conclude that throwing money at government education and liberal education policies don't work.
For those who say it is the blacks and hispanics causing California to be worse, the facts are at http://quickfacts.census.gov/qfd/states/
It isn't because of the rate of blacks and hispanics. 6.7% and 36.6% of Californians are black and hispanic or latino respectively. By comparison, 11.9% and 36.5% of Texans are black and hispanic or latino by comparison. However, Texas is doing significantly better.
