We were doing lessons with Cathy almost 5-6 months and I should say that one of the best classes I have ever had. She has her own methods and she definitely finds the right books and materials to learn. Don’t even need to mention that she is reachable all the time when you want to ask something and she definitely follows the homework she assigns. For sure I’ve learned a lot and even today I use the same materials and books when I want to practice again.
