Does the extreme point offset the Beijing exam?
Testing.

The problem of extreme point deviation is a very important and difficult type in the finale of college entrance examination. There are two ways to deal with them. One is the symmetrical method, which has complicated ideas and many mistakes, and needs to be dealt with by learning from God. The second is the logarithmic mean inequality method, which can be easily solved by using very advanced second-order conclusions. It should be noted that the logarithmic mean inequality has two parts, which need to be proved after use, which will make the thinking clear and easy to handle.

Beijing Mathematics Volume is an independent proposition. Many Beijing candidates think that the math test is the most difficult one in the college entrance examination in recent years. I don't understand the last big question. The conditions given in the test questions are a bit confusing. You need to read the question several times to understand it, and the answer is not easy. There are also some partial questions, which are the types that are rarely tested at ordinary times. The conditions given in the question are not direct. For example, a problem of solid geometry needs a few more steps and more calculations to be deduced. There is a big gap in the math scores of Beijing candidates.
