Call the school that she is interested in and see what is required. You will have to withdraw her from the one she is currently in. My daughter wanted to be home schooled after her Sophomore year. She took all her classes on line with Keystone National High School. Worth every penny of it. She was motivated, there were tutors available as well as teachers.It is not as easy as one thinks, home schooled youngsters are brighter, more motivated, and excel in most of their classes. Her exams were done on line, open book. Most work done was in essay form. She was involved with the Youth Symphony as well as the Chicago Youth Chamber Group. Very busy person. I had to withdraw her, sign a few papers and off we went! Never any regrets. Check it out if she is interested.
