Some students have even been brushing some questions that are completely inconsistent with the way and difficulty of the real questions, resulting in not realizing the real difficulty of the exam. So when it comes to the exam, we are caught off guard, and disastrous results are common.
In order to let you choose less reference materials, today I will give you a guide to the use and evaluation of common mathematical materials in the market.
Firstly, the dimension of evaluation is explained, that is, what kind of GRE mathematical data is good data.
1, consistency with ETS real questions: real questions are always the best. If it is not the real question, it must be close to the actual question.
2. Difficulty classification: It is more convenient for students to evaluate their own level by marking the difficulty questions.
3, the proportion of problems: as few easy questions as possible, as many problems as possible. After all, it is the difficult part that hinders everyone from taking the exam 170.
4. Answer and analysis: You must have a complete answer and analysis, even a video explanation, otherwise you won't even know where you are wrong.
According to the above four dimensions, we evaluate the data of brushing questions widely used by users in the market. If the content is too long, you can pull it to the end and summarize the key points with a picture.
Description of scoring rules: each dimension ranges from one star to five stars, with five stars being the highest and one star the lowest. Everyone should make a comprehensive evaluation according to all dimensions.

User guide:
Since the summer vacation of 20 18, mathematics has become very difficult and tricky. So from 18 to now, we have collected the machine classics recalled by the students in the examination room, and selected the questions with moderate difficulty or above to form this data, which has been updated to 360 questions at present.
Because it is a memory version, the topic is written in Chinese, but the knowledge points contained in it are exactly the same as those in the exam.
It is suitable for the sprint stage before the exam and can be used as a topic with the same difficulty as the exam.

Answer and analysis: one star?
Note: The analysis written by foreigners is difficult to understand.
Comprehensive recommendation index: two stars
Summary:
For the students who have just started preparing for the exam, they can start with some difficult topics, such as GRE math perfect score, but when they hit 170, they must break through a lot of questions, such as GRE math problem 170 and GRE math machine classic 400.
In addition, doing as few questions as possible that are inconsistent with ETS ideas will make you misjudge the test questions and even have a negative impact.
In the case of limited preparation time for mathematics, materials with high comprehensive recommendation index are preferred. Of course, if you have enough time, you can read all the materials mentioned above.
Comprehensive evaluation of 4-star and above materials is recommended for students to use in the preparation process. This time, I also gave the students a data packet. Students in need can ask me for it. I wish everyone an early math 170~
