Why did she do this? In her opinion the public school offered a better education in the fields of math and science. The private school was much stronger in languages and English, but weak in music, AP offerings, lab sciences, and upper level math. The highest they went to is AP Calc AB. She can and will go further in her public school.
The result on her SAT showed she made the right choice. Her newest SAT scores were 710 quantitative, 780 verbal, 720 writing and she already has a verbal offer of full ride (including most of room and board) at her 1st choice private college. She is also the 12th ranked FHorn in the state of Virginia. So, we're doing okay with the public schools here in Virginia
Again, you may want to read all of my posts here, I have never said there were not exceptions to the rule. There are always exception to any rule. I still challenge you to read “The Closing of the American Mind” before you celebrate too broadly.
