"One way to cut your family's education costs is to enroll the children in virtual public schools.
Though not available in all states, a number of companies have started virtual schools that conduct elementary- and high-school classes online. Students take the classes at home, usually tuition free. Funding for the programs typically comes from the state.
K12 Inc., based in Herndon, Va., operates virtual public schools in 21 states. Its Web site, www.k12.com, shows where. K12 gives each of its high-school students his or her own computer. Its curriculum includes Advanced Placement classes."
