It is strongly recommended that you spend two hours reading the math review of OG 12 and reading sections 4. 1, 4.2, 4.3 and 4.4. It can be said that it is multifaceted.
You need to do the same math preparation over and over again. For example, go to continuous model test preparation.
Do the math part of 1 for many times until 5 1, find the feeling of 5 1, read the feeling of English math problems, and consolidate math terms.
At the same time, we should be familiar with the problem-solving steps of various types of questions, such as DS questions, and develop a fixed problem-solving habit. Consider the condition 1 separately first, then look at the condition 2, and then put the condition 1+ condition 2. If you think you are not ready, give a counterexample. Combine these questions and draw Wayne's schematic diagram. This mechanical step can often overcome the mistakes caused by carelessness to a great extent.
At the same time, we should conscientiously sum up our own types of wrong questions. You will find that it is possible that the understanding of the meaning of the question is wrong and the calculation is careless, which leads to the fact that the condition 1 and the condition 2 of the ds question are equivalent, or you are unfamiliar with a certain knowledge point, or some kind of problem-solving methods are too complicated.
You must choose a suitable time for the exam, which is usually enough after a week of changing the topic.
Be sure to do the machine classics carefully one week before the exam.
You must do the first 300 questions carefully before you answer them. You must also do it with a purpose. Think about the test sites and the ideas of each question, and at the same time
Compare the answers compiled by NN, see what is missing, and pay attention to the variants.
When you are tired of reviewing oral English, I suggest you go to the forum to see difficult posts and popular posts.
Looking at the dog discussion posts listed separately can consolidate some difficulties. For example, the calculation method of probability, permutation and combination problem, Wayne graphic solution of set problem and summary of remainder problem.
spot checking
Answer the first ten questions slowly. You may not be familiar with dogs or think the questions are too simple during the exam, and the answers can be seen at a glance. I suggest you answer it again and check it again to ensure that you will not lose unnecessary points because of carelessness or variation. If you are really stuck, don't be depressed, because even if you get 1 to 2 questions wrong, you may still get 5 1 point.
