You can buy "May 3rd" or "Qidong", both of which are classic, and the quality of the title is guaranteed. I am also in Grade Three, and I usually brush "May 3rd" in my math exercises. If I improve, I can brush the "top student question bank", mainly because it is difficult.
Don't do all the "May 3rd" questions. You have to sprint in the third grade, and you don't have enough time and energy to do one after another. Don't waste your time on simple things, just pick the slightly difficult ones, and you will make progress only if you have challenges. Don't ask for much, try to be one-on-one. Don't skip the last question or two, try to do it yourself first. I really can't think of the answer. If you understand them, close the answer and write it yourself. As for the basic questions, make sure that you get almost the right answer, 90 points, which is basically the same as the slightly difficult questions.
In order to ensure the quality of the class, teachers must listen carefully and the assigned homework must be completed carefully and correctly. The classroom assignments assigned by teachers are generally the most basic and simple, and it is unreasonable to make any mistakes. The formula must be memorized. You can sum up the formula you have learned, then recite it and recite it again. In fact, there are really not many formulas to remember in junior high school mathematics.
It is still very useful to brush the real questions and simulations of the provinces as much as possible when sprinting.
Relax during the exam, and nervousness will affect your grades. Don't think too long about the simple questions in front, do them quickly and make time to check them.
Be hard on yourself at ordinary times and quit everything that affects your study. It is important to strictly control the time you spend playing mobile phones.
Finally, I wish you progress in your study! If the answer is helpful to you, I hope to adopt it!
