(1) When using draft paper, don't scribble the draft at will.
On the draft paper, it is necessary to write down the title number and the drafting process in order, which is very conducive to the subsequent review one by one. There are at least five minutes left in the 35-minute exam. When checking, you only need to look at the stem of the question, and then check your own deduction calculation process, which is very efficient. Don't mess up the draft paper.
(2) Be cautious.
See clearly what you are asking (year/month, individual/whole, how much more/how much less, etc.). ), you should think clearly in all directions (may be negative? ), try to substitute data from the middle option.
The above content gives candidates a detailed introduction to how to use the draft paper of GRE math exam, hoping to help them. Candidates are advised not to write anything on the draft paper before the exam, so as not to cause the teacher's unreasonable attention. I wish the candidates success in the exam.
Tips: GRE mathematical substitution method
What is substitution?
The so-called substitution method refers to the practice of directly substituting the specific data given by the topic option into the topic and finding the correct answer through reverse verification. Many students are used to solving problems by reading questions, listing formulas and calculating in the normal process, while the substitution rule can be said to be the opposite.
When is the right time to solve problems with method of substitution?
In GRE math problems, many problems often have relatively complicated and long stems. Candidates need to spend a lot of time reading and understanding questions, then sort out ideas, list formulas, and then start calculating. The whole problem-solving process is time-consuming and laborious, and it is difficult to guarantee that the answer can be worked out once. If you directly use the substitution method, you can directly verify the conditions from the answers, and often you can find the correct options faster, saving a lot of time in solving problems. Therefore, if you encounter a long math problem in the exam, it is a more efficient choice to solve it with method of substitution.
