Sophomore math, is it better to do a reference book twice, or buy another one to do it well?

Do it twice in one book! I'll get better in the first place, just try it!

Of course, it's better to do it twice, unless you are a prodigy, and there is no mistake when you do it the first time, otherwise you have to start anew, that is, consolidate yourself, and fill your blind spots, these are the experiences of people who have come over, and remember that you have done several workbooks, not to measure the depth of your review, the key is to look at the quality, a book, when you learn well, do the same thing, make a workbook, is to find your own shortcomings, when you find out, the first thing that comes to mind is not because you should continue to find other shortcomings It's about overcoming the shortcomings you find, otherwise you're going to make 100 copies in vain.

It's good to do a book twice. And you have to do it seriously every time. If the material works for you and you really get it right, then you're pretty much good for all the same types of questions.

And if you can, do the books a few more times, and read the concept together, so that you remember it very clearly After all, the foundation is the most important, I used this method from the second year of high school to the third year of high school, and my grades improved by nearly 40 points, hehe, it is definitely a very powerful experience.

Finally, I wish you success in your studies

One time is enough, pick another one, it is recommended to do the college entrance examination questions "Tianli 38 Sets" is good.

It depends on your own ability, if you think the teacher's book is not too difficult for you, then you can buy a book that suits your own level. If the book you have at hand is still difficult for you, then try to understand this book first, and you are considering buying a new one.

My experience as a senior in high school

If you can do all the questions in this reference book, buy another one. In fact, the general reference books are similar, the key is whether this reference book is good or not.

Buy another copy so you can see the different question types.

o(∩_o...This is a famous quote from the old class.

Hee-hee......

After doing it twice, buy a copy!

Recommend the "Handbook of Heavy and Difficult Points", in fact, the method is the method of doing the questions, and the sensitivity to the questions, but then again, if you can understand everything in that book, pay attention to the real understanding, then there will be no problem in the college entrance examination.

The two books are more or less different! Buy another copy!

Buy a five-star question bank, it's pretty good.

"Sets and Functions", "Trigonometric Functions", "Inequalities", "Number Sequences", "Complex Numbers", "Permutations, Combinations, Binomial Theorems", "Solid Geometry", "Plane Analytic Geometry", Compulsory 1.

"High School Mathematics Compulsory 1", that is, the abbreviation of "General High School Curriculum Standard Experimental Textbook - Mathematics Compulsory 1 - A Edition") is a book published by the People's Education Publishing House in 2007, and the author is the Research Institute of Subject Materials of the People's Education Publishing House and the Research and Development Center of Middle School Mathematics Curriculum and Textbooks. This book is the first teaching aid for the compulsory high school mathematics learning stage sequence.

2. "High School Mathematics A Edition Compulsory 2" is a book published by the People's Education Publishing House in September 2007, and the author is Wang Shenhuai. The main content of the book is to understand spatial graphics, and cultivate and develop spatial imagination ability through the overall grasp of spatial geometry.

3. "High School Mathematics Compulsory 3" is the third book in the new curriculum standard high school mathematics compulsory series, which is divided into two editions, A and B, and is published and distributed by the People's Education Publishing House. The main content of this book is to explain and summarize the knowledge of algorithms, statistics, and probability.

4. "High School Mathematics Compulsory 4" is a book published by the People's Education Publishing House in 2007, the new curriculum standard textbook, the fourth in the compulsory series, and the general high school curriculum standard experimental textbook Mathematics Compulsory 4 A edition.

5. "High School Mathematics Compulsory 5" is a book published by the People's Education Publishing House in 2006. This textbook includes three chapters: "Solving Triangles", "Number Sequences", and "Inequalities".

The textbooks of mathematics, liberal arts, and sciences in the second year of high school are different, and there are differences across the country, which are roughly as follows:

1. Science: Compulsory 2 (Preliminary Analytic Geometry and Solid Geometry), Elective 2-1 (Conic Curve), Elective 2-2 (Principles of Classification and Notation), Elective 2-3 (Permutation and Combination).

2. Liberal Arts: Compulsory 2 (Preliminary Analytic Geometry and Solid Geometry), Elective 1-1 (Plane Geometry), Elective 1-2 (Principles of Counting).

Among them, the elective 2 series are mainly functions, statistics and probability, logic, conic curves, space vectors and geometry, derivatives, reasoning and proof, number system expansion and complex numbers, and counting principles.

Elective 4 series is mainly topical, such as coordinate system and polar coordinates, selected lectures on geometric proofs, etc. The other 4 series belong to the category of elective courses, such as inequality selection, number series and difference, etc.

In the second year of high school, students will learn the key knowledge of elective textbooks: space vectors, reasoning and proof (focusing on mathematical induction), plane analytic geometry, derivatives, and counting principles.

The number of mathematics textbooks in the first year of high school will vary depending on the textbooks used in different places, and the teaching materials of the people's education version need a total of eight books for the learning version.

They are: 1. Compulsory:

High school math is compulsory.

1. High school mathematics is compulsory.

2. High school mathematics is compulsory.

3. High school mathematics is compulsory.

4. High School Mathematics Compulsory 5.

2. Electives: High school mathematics electives.

1. High school mathematics electives.

2. High School Mathematics Elective 3.

I studied High 1 Upper: Compulsory Lower: Compulsory High 2 Upper: Compulsory 3 Elective High 2 Upper Liberal Arts 1-several, Science 2-several The teacher said that because the compulsory course involves solid geometry, it is too difficult, so I learned it later.

Revise the two electives (different regions) from 2-1, 2-2, 2-3 and 4-1, 4-2, 4-3, 4-4, 4-5

There are a total of nine books on high school mathematics in the new college entrance examination

Sets and Functions", "Trigonometric Functions", "Inequalities", "Number Sequences", "Complex Numbers", "Permutations, Combinatorials, Binomial Theorems", "Solid Geometry", "Plane Analytic Geometry", and the Regimental Hall is a compulsory course.

5. Electives 1 to 4.

Of course, when reviewing mathematics in the third year of high school, you have to read the textbook, because the knowledge in the textbook is the most basic and important knowledge. Although the teacher will prepare a variety of materials for the students during the review in the third year of high school, and the students will also buy a variety of exercise books, the textbooks are still not forgotten because the textbooks are very important. If you choose to forget the relevant knowledge in the textbook, then it is likely to lead to big problems in learning, so you must remember not to ignore the dry textbook.

Some students think that the most important aspect of math is to do problems, so they think that they only need to do problems, but this is not the case. Because if you ignore the textbook in the subject of mathematics, it is very likely that there will be a big mess in the exam, so you must also remember to read the textbook when reviewing in the third year of high school. Only in this way can you make your review effect better, and you can better learn relevant knowledge, that is to say, the review of the third year of high school is inseparable from textbooks.

When a professional teacher leads students to review the third year of high school, they will start with the textbooks, and they will learn the textbooks they have studied in high school from the beginning to the end, so that students can understand more about these knowledge and master more things in the learning process. Therefore, students should also pay attention to contact the textbook as much as possible when revising, so that they can get better gains from the textbook. <>

That is to say, students should not only read the textbook when reviewing, but also carefully hide and celebrate the textbook, only in this way can their grades become better. If you encounter some new knowledge when reading textbooks, you should also choose to write down these things, because these are all ignored before, if these problems really appear in the college entrance examination, then your own learning is particularly meaningful. Therefore, students must find the right way to study, only in this way can they get better results.

Yes, but you should pay attention to the combination of work and rest, you must arrange your time reasonably, and you must do a good job of reviewing the work when you are hungry. Do more relevant exercises.

Yes, because review is a process of checking and filling in the gaps, we found the formula theorem that we don't remember in the process of reviewing mathematics, and we should consult the textbook in time and remember it in time.

You can choose to read the textbook, because the content of the textbook is very basic and very easy to learn, so we can choose to read the textbook.
