Virtual schooling involves learning online as opposed to learning in a classroom with other students and a teacher.  It can cover the same curriculum that is taught in person, but the learning is done either at home or wherever a student has computer access.  Virtual schooling can be for anyone, a student who has been expelled from the traditional school, temporarily or permanently.  It can be for students whose parents want to keep them out of traditional schools due to health reasons or behavior issues,  or just as an alternative to traditional schooling
