And as a home-school mom and a music teacher CTC makes me so happy that I just have to sing about it. No lesson planning or fights with my children, self-grading test and video lessons. Switching grade levels is super easy. These are the best things about CTC. Keep up the great work CTC. Thank you so much!" | CTCMath | Facebook
