Granite Mountain has helped me to get all the credits that I need to graduate. They have made it really easy if I miss a deadline to register for a class then I can just take the class through the charter and do it online that way I don't have to wait till the next semester to take the class. I can take dual enrollment classes and they helped me to find good teachers and courses that will help me in the future. I even have enough credits to graduate a year early but I'm not going to because I can just take college classes and get credit for them.

Granite Mountain Charter School is a great program for those who want to homeschool their children but don't have the resources. GMCS has pros and cons like any school but the good outweighs the bad. However, one thing I would want to change is more student body activities such as school dances and student interaction.
