The proportion of gifted students will not be so high, especially in the primary school stage where there is no diversion, and the gap between urban and rural areas is not so big, otherwise how can county high schools achieve such a high rate.
The gap between urban and rural areas is particularly obvious in the primary school stage, many township children have never seen the topic, urban children do it one by one, and even some parents take it to test other adults, no, this is my baby's second grade question, you will do no, but after getting a positive answer that will not do, most of them will have a strong sense of pride, and mutter, the current children are too difficult, the current children are too smart to compete, it seems that an ordinary primary school, a group of future geniuses are competing.
But in primary school, there is indeed a feeling that the lower limit of urban children exceeds the upper limit of rural children.
The real situation is that those so-called problems are just learning specific skills outside the textbook, that is, some agreed formulas, if you have not been exposed to such formulas, then the formula itself needs to rely on your own thinking to deduce, this difficulty is obviously too much, if you can fully deduce, that is genius.
It doesn't make sense to compare yourself with others with open software. This is the case with the Olympiad, some famous junior high schools use the Olympiad as an admission evaluation criterion, and may select some children with good scientific thinking, but most of the children are just formula applicators who accompany the run. The biggest effect is to give birth to the popularity of Olympiad training.
This situation is also true in junior high school mathematics learning, geometric proofs that should pay attention to complex logical reasoning have been replaced by various pattern training, and the mode of quickly getting high scores greatly reduces the process of thinking deduction, and such high scores also have no excessive reference value.
The difficulty of the high school entrance examination is not high, the limited difficulty is not comparable, and the effect of extracurricular training is also inflated to a certain extent.
