We are two years with ByJu's Math and one year with ByJu's art. Amazing programs, professional teachers. We are very happy. Prices are below $15 per hour one on one classes. Very budget friendly. They have very strong reward system for students - points and badges. Before signing up you could negotiate sign up bonus, like discount for package and Amazon gift card. Our Math teacher at BYJU'S is Ritu Agarwal. She is very patient with our teenager and very helpful. Highly recommend.
