Chemistry in the third year of junior high school is terrible.
High school is very good, and the science is all about chemistry.
Now I'm studying chemistry and biology in college!

Anonymous users2024-02-10There is definitely an impact, but it is not significant. Many of the things in high school are the same as those in junior high school, but they are more in-depth and detailed. Therefore, if you learn well in junior high school, you will be relatively easy to learn in high school.
If you don't do well in junior high school, it's okay, as long as you study hard in high school, you can pull it. However, please note that if you do not study well in junior high school, it will inevitably affect your confidence in high school.

Anonymous users2024-02-09Junior high school cultivates interest, high school teaches knowledge, as long as you work hard, there will be no impact, if you relax, no matter how good junior high school is, it is useless!

Anonymous users2024-02-08Hehe, I'm a junior high school student like you.
I think chemistry in junior high school is very important.
It is a basic course.
If you don't study well now.
Then not to mention the later ones.

Anonymous users2024-02-07Definitely, I'm a sophomore in high school, and I think the main reason why I'm doing well in chemistry now is because I'm doing well in junior high school.
After all, knowledge has stages, and if you can't solve simple problems, how can you make breakthroughs in complex problems in the future?
However, as long as you work hard, I believe you can still make up for it.

Anonymous users2024-02-06As far as I know, there will be an impact, but it varies from person to person, for example, I am not very good at chemistry in the third year of junior high school, and now in the third year of high school, my chemistry scores have always been in the top few in the school.

Anonymous users2024-02-05Absolutely! The knowledge of junior high school is the foundation, and the things actually learned in high school are the same as those in junior high school, but they are further deepened on the basis of junior high school, so the foundation is very important, otherwise it will be more disadvantageous when you reach high school.

Anonymous users2024-02-04No. High school chemistry will be repeated in junior high school.

Anonymous users2024-02-03It shouldn't have too much impact, and besides, chemistry in the college entrance examination is the easiest in science, you don't have to worry too much, chemistry in the college entrance examination is all about high school, and it rarely involves junior high school.

Anonymous users2024-02-02Yes! Ions, acids, alkalis, and periodic tables in junior high school chemistry are very important, and it is recommended that lz study should not be lazy, and should be solid in order to succeed!
Good luck with your studies!

Anonymous users2024-02-01Junior high school physical chemistry is not good, as long as you are willing to work hard, grasp the basic knowledge, do more exercises, do more summaries, you can still keep up, you must be full of self-confidence, take advantage of the holidays, and catch up with junior high school physical chemistry.

Anonymous users2024-01-31It depends on the individual.
High School Physics Knowledge vs. Middle School Physics.
Knowledge is almost irrelevant,(For example, distance and displacement,Speed and velocity are the different concepts of junior high school and high school)Of course, the electrical part of high school requires the basic knowledge of circuits in junior high school,But the difficulty of high school physics is really much higher than that of junior high school,I am a girl who thinks more than liberal arts,99 points in physics in the high school entrance examination,But high school physics has really become a big difficulty (not that you don't study seriously) or it depends on the degree of effort and subject thinking。
Chemistry is not very relevant to junior high school knowledge (except for some of the most basic chemical equations.)
and chemical elements) in junior high school are all back-to-back, but you may learn more chemical equations in a week in high school than you learn in a year in junior high school (a class of chemical reactions.
put together, so high school still has to understand the essence, and not rote memorization) and then there is organic chemistry
