Personally feel that the basic concepts of mathematics are very important. Understand this, and then do the problem, you can be clear.
Personally, I think it is advisable to look at my previous homework. You can try to look at the problems you usually do wrong, recall the problem-solving ideas at that time, and compare and improve with the correct problem-solving methods.
When you usually do the questions, you can circle the good questions and more kinds of questions, so it is much more convenient to review before the exam.
You can also copy down the key things and take notes, no matter what the process is, just look at it.
In fact, mathematics is not that difficult. The key is that your usage is clever and unfortunate. (This is the suggestion of other netizens on the Internet)
As for me, I think this is an incredible question ~ ~ I also want to know that we are also struggling with Grade Three. . But personally, I think your efforts just hit luck and turned into success. . To do mathematics, we must first have a solid foundation. Basically, you can do a few difficult questions, such as the too difficult finale. If you do the first few small questions, it doesn't matter if you leave the most difficult one blank, it won't exceed a few points. That's it, well, the usual efforts are in vain ~ ~
If it is adopted, it will be a great honor and you're welcome ~ ~
