Challenging online cyber schools?

Question

What are the best and most challenging online schools for high schoolers?

Answer 1

University of Missouri has a very good program (https://www.cdis.missouri.edu/) , as does Allied National High School(http://www.alliedhighschool.com/), I use both in the Cyber Class I teach.

Answer 2

Alpha Omega Academy is very challenging.  They go in-depth into every subject they teach.  I've learned more with them this year than I ever dreamed of learning in a public school.  This is my first year with them, and I love it.
