I have been raising children in their home 1 for many years. I can't say how good the effect is. I can only say that I didn't like math at first, and I got more than 50 points in every exam. Finally, after 1 years of training, I became very fond of mathematics and always studied with me with some Olympic math problems. Finally, my children got full marks in mathematics in the 20 19 senior high school entrance examination.
