1. Math review includes most math terms that may be encountered in the exam. As long as you understand the math review thoroughly, you don't have to spend time memorizing words.
Mathematics review, you can see an example of sufficient conditions for the order of questions to be DS. In DS problem, the solution of special interrogative sentence must be unique and sufficient. For general interrogative sentences, generally only answer yes or no.
Be sure to master the most basic mathematical vocabulary. Gmat wants to get high marks in mathematics, provided that the words are correct.
2. The calculation of variance in 2.GMAT mathematics is a bit complicated, and the problem lies in poor understanding ability and too much trouble in calculation.
For example, the average score of the two classes is 70, which looks similar. However, when analyzing everyone's grades, we can find that some students in Class One got 100, 90, 60 and 30 points. The scores of each student in Class Two are 60 to 70, with little difference. This shows that the fluctuation of class one's performance is greater than that of class two, and the distribution is not concentrated enough.
Try every answer, the stupidest way is sometimes the fastest way. This method is not widely used, but it has high accuracy. As long as there is an answer that matches, it will be done. Especially when there is a question similar to mine in the option, the speed will be faster.
4. at 4. To prepare for the GMAT math exam, we should look at the requirements of PS questions clearly, and see whether it is a ratio or a numerical value. Don't confuse the front and rear objects when calculating the proportion. In addition, for the topic of commodity discount, whether the discount is a discounted part or a discounted price should be carefully read to clarify the requirements of the topic.
In the GMAT math exam, some questions are not difficult to calculate, but there are often some confusing information, so candidates must read the questions clearly before answering.
Some problems in 6.6. The required range of GMAT math test is greater than the numerical range. When doing the problem, we must consider the interval of-1, 0, 1, and we can't just take 0 as the dividing point, which will be incomplete.
7. For GMAT mathematics, you must carefully look at whether the question involves integers. If the problem doesn't involve integers, don't assume they are integers. Even if the given conditions are integers, you should answer them according to the requirements of the question.
