No. I use my own materials as well as textbooks published by Difusion. Along with the purchase of your lesson plan, you will have free access to the books and also to the interactive activities for you to practice at home. Materials used in the classes will be previously agreed upon with you. You don’t need to buy anything extra to attend classes, since everything will be provided by the teacher. However, if you want to buy a textbook to practice by yourself at home I highly recommend you purchase at Campus difusion.
