The mathematics correlation between primary school and junior high school is not too strong, but the way of thinking, attitude and habit towards mathematics learning have influenced junior high school mathematics learning. For a child, if there is only Grade Three left in the nine-year compulsory education, then simply follow the original trajectory and don't try to turn over again. This difficulty coefficient is too large for most people to complete. This kind of plot may exist in real life, but it is rare, and it often happens in fantasy novel.
Don't be fooled by some touching lies in society. If you don't study at ordinary times, you will be lucky in the future. This kind of joke is just deceiving fools, etc. Deceive those who often don't study hard, and then let them continue to work hard. This is a fairy tale. But whimsy can get something for nothing, and whimsy can suddenly become the smartest person in the world and know what to learn.
The math difficulty of grade three is much more difficult than grade three, grade one or even grade two, which can be said to be not an order of magnitude at all. If you don't study hard at math in grade one and grade two, it's obvious that you won't do well in math. It is very difficult to achieve counterattack on such a weak basis. First of all, you have to fill in all the shortcomings of knowledge and lay a solid foundation. As we know, in the second grade, the content of mathematics learning has greatly increased. I think it is difficult for you to review all the knowledge points you missed in the third year of high school, let alone overcome the knowledge difficulties in the third year of high school.
I think it is impossible for a person who didn't study math well in grade one and grade two in primary school to suddenly wake up in grade three and try to learn math well. As the saying goes, Rome wasn't built in a day. You have developed a "mixed" state, and it is difficult to summon up the courage to do something that bothers you in a short time. I'm not saying that you can't learn math well in your life, but that it's hard for you to turn around Gan Kun immediately in a limited year and maintain a strong fighting spirit and continue to study math. If the time is extended to three years, I think it is ok, but if I only give you one year, I don't think you are so good.
