Online High School FAQs

"I have been with Keystone for two years, and as my high school experience is coming to an end, I wanted to find ways to make my last few days memorable. My parents found Keystone when I was going through a tough time in my life, where public school just didn’t work for me anymore. I now have a 3.0 GPA, and on my way to graduating."
