Students of my generation may be similar to children in your. There are many concepts and difficulties in high school mathematics. At present, most schools in Shenyang are learning very fast, and students easily fall behind, especially your children fall behind in Grade One, Grade Two and even junior high school. It's hard to catch up. Finding a few mentors doesn't mean that all mentors are bad. Don't just trust your teacher to teach good students. In view of your child's situation, I still suggest that you can let her learn from the most basic high school knowledge instead of following the school! This is very important. One of the big taboos in learning is that she thinks the problems she is learning now are very difficult. It's no use telling her these difficult and intermediate questions again. Sometimes, on the surface, you ask her, and she says she will do it. She understands, but she forgets later. The most fundamental reason is that the most basic knowledge is not understood and mastered. Personally, I suggest that students with poor grades should not follow the school to do college entrance examination questions. I suggest you buy the purple version, the white version and the Handbook of Basic Mathematics for Senior High School published by Wang Houxiong. From now on, learn from the basics, even from textbooks, understand the concepts in textbooks first, and then do the questions. This is the right choice.
Because of time, that's all Please add other questions. I mean, in view of the fact that such students are still based on basics, it is the best strategy not to put too much pressure on children before they lay a good foundation.
There are still half a year before the college entrance examination, don't worry, stick to it and never give up!
