My child just went to the foreign training center of Xida University. Before they went, they especially hated the Olympiad. They always tell me, mom, I don't like learning Olympic math. As parents, our olympiad is not very good, so we can't coach her. The school teacher often told us that your children were afraid to ask questions in class, and it was really helpless at that time. Later, I was introduced to the foreign training center of Xida University by my colleagues, and my Olympic math scores improved a lot. I think it's money well spent. You can do it.
