Happy Parents Feedback
Classbuk is doing an amazing job for online classes. I am impressed by the way their selected teachers engage with my daughter Shairin. Shairin looks forward to her classes with Classbuk
From classical Indian dancing, piano, to art and yoga, they pick the finest teachers who form an immediate connection with the child. Utmost care is taken at each session to ensure it meets customer satisfaction.
The classes with Classbuk have been so worthwhile. My daughter is learning western music from the teacher through Classbuk and it has been a great experience. The supportive push by the teacher helps the child to build confidence and is a big motivation.
Saanvi is eager and is looking forward to her coding class every week with Ms. Seema. Her favorite part of the class is when she can play the simple fun games she has created. It’s a great opportunity to have this available at Classbuk as a skill-building topic, with a small group and personalized experience.
