Benefits: Take math first. I had already previewed what I had to learn in junior high school for three years when I was in grade one. I tell you in a low-key way: I started teaching my cousin who is not very good at math in grade three when I was in grade one ... In grade one, it doesn't seem to have much practical significance to study in advance. Don't worry, keep watching. ...
By the second day of junior high school, I had finished learning the vector we had learned in senior high school. At this time, the benefits are obvious. When I was doing geometry proof problems in junior high school (mostly proving the congruence of triangles), I could solve geometry problems quickly with vectors!
In the third grade, I became more and more addicted to advanced learning and neglected other subjects. After chasing for a semester, I finally caught up with it, and then I continued ... At that time, I remember that I studied quadratic function in the third grade, and I used analytic geometry every time I met the finale of quadratic function. As a result, it is very simple to do junior high school questions with high school knowledge.
Later, I took the senior high school entrance examination. I don't need to say LZ should have guessed it. Because of partial subjects, I naturally didn't get into a good high school
I'm a freshman now. Because I still study in advance, I can't help but use differential (derivative) to solve the monotonicity problem every time I encounter it. Almost omnipotent! Although the math teacher said to me personally: Zhou, your math is already very good, I hope you can pay attention to other subjects. But I am still dishonest. After all, I have never heard of any teacher who would tell his students not to study his subject so hard ... Later, I used space vectors to do solid geometry, which was almost omnipotent! Now I have begun to preview topics such as momentum and friction, and I have also considered previewing definite integral, but my father doesn't give me …
Finally, tell you, because my father is a university professor, he taught me all my further studies, LZ, you have to think clearly! It's good to study in advance, but the key is that your foundation must pass, and don't leave other subjects behind like me, so that you won't lose. The college entrance examination can't just take math and physics!
