The familiarity with knowledge points is divided into two parts. First, be familiar with the formulas of new GRE mathematics, such as the graphic area formula in geometry, such as the relationship formula between roots and coefficients in equations, factorization formula and so on.
The meaning of familiarity is that when reading a topic, candidates can turn the language of the topic into a formula in their minds, thus speeding up the problem solving, instead of thinking: What does the topic mean? The only way to achieve this ability is to do more problems. Even if you feel that your math foundation is not enough, 3000+ questions in books and textbooks are enough to improve this ability.
For example, let's look at a topic: (numerical comparison question) The vertices of a fair triangle are all on A.
Round.
The length of one side of a triangle and the diameter of a circle.
When you get the GRE math problem, you should form an image in your mind: an equilateral triangle with a circle inside it. Then you can work out all the values. Don't look at the topic. Let's mentally calculate the relationship between the radius of a circle and one side of an equilateral triangle: 1: √ 3. Other relationships, such as the relationship between the area of a triangle and a circle, can also be calculated. At this time, let's look at the two limbs of the topic: the side length of a triangle and the diameter of a circle (note that the diameter is not a radius), and their ratio is √ 3.
2 (these basic values should be known) then it is obvious to choose B.
In short, it is very important to read and predict the content of the stem when reading the stem in the GRE exam, which can greatly speed up the problem solving. Six-step system of heaven
TSSS originates from experience, responsibility, mission, inspiration and genius, and fully embodies the wisdom of every heavenly person and the successful admission experience of thousands of prestigious schools. On the basis of introducing the advanced consulting service mode of the world's top consulting companies and the western vocational evaluation system, Tiandao has created a brand-new service system for studying abroad in combination with the actual confusion and needs of applicants during their study abroad. The purpose of "Six Steps to Heaven" is to break the traditional service mode of studying abroad, attach importance to employment, attach importance to scientific career planning and emphasize "fishing". Assist the applicant to Create a competitive advantage, which he never realized when applying for a prestigious school.
Your own advantages). The goal of Tiandao is to become a reformer and a new rule maker in China's study abroad industry. We should break the existing habitual thinking and make the same changes and innovations.
In another case, it is very important to remember specific values, such as the value of pi 3. 14. In many circle calculation problems, the values of the circumference and area of a circle are basically multiples of 3 14, such as
628, such as 157, and so on. There is also a special right triangle angle relationship, 3, 4, 5; 1、 1、 1.4 14; 5、 12、 13; 1,1.1732,2, etc. It is best to memorize them to reduce the calculation time.
In this way, the problem-solving time will be changed from 1 minute to less than 30 seconds, so the whole written mathematics part should be finished about 10- 15 minutes in advance.
However, the actual problem-solving time is often only reduced by about 5 minutes. Why is the actual time estimate different from the theoretical time estimate? This difference is that many questions are not just about a knowledge point, but comprehensive questions. More importantly, the reading time of five chart problems and other application problems far exceeds the budget of 30 seconds. This requires students to do two things well: quickly condense a mathematical relationship from the long stem of the application problem; When doing chart problems, you should be clear about the quantitative relationship when you skim the chart for the first time, instead of focusing on specific numerical values.
The above is Bian Xiao's analysis of math time in GRE test. Candidates must remember that the GRE exam is very tight, and even simple new GRE math candidates can't waste time. Do the GRE math problem as soon as possible, don't put it off.
