Of course it matters. Three-dimensional geometry in the college entrance examination accounts for 20-30 points, which is bound to be a big problem. Solid geometry is difficult because many people, especially girls, have never been trained in solid geometry thinking since childhood. If you think with solid geometry, solid geometry is actually the simplest plane geometry in junior high school! Solid geometric thinking can only be cultivated by learning solid geometric models. It is a wise choice to buy a solid geometric model.
