Many people will think that counting one is the most difficult, counting three and counting two is the easiest. Indeed, because of the small scope of investigation, counting two will be relatively detailed, but relatively speaking, it will be easier to review the knowledge points.

However, counting one is not as difficult as counting three. After all, the two volumes focus on different areas of investigation. Some people think that counting one is much more difficult than counting three, but it is not, and the areas of concern are different.

One or two differences in postgraduate mathematics

Mathematics for the postgraduate entrance examination-linear algebra, advanced mathematics, probability theory and mathematical statistics all need to be tested, which is relatively comprehensive and difficult, with linear algebra accounting for 22%, probability theory and mathematical statistics accounting for 22% and advanced mathematics accounting for 56% at most. In the 123 middle school, the scope of investigation is the widest, and basically the whole textbook has to be tested.

There are only linear algebra and advanced mathematics in the second entrance examination of mathematics, of which linear algebra accounts for 22% and advanced mathematics accounts for 78%. The range of linear algebra in Mathematics 23 is roughly the same, while the number two in advanced mathematics has been deleted a lot, such as vector algebra and spatial analytic geometry, triple integral, curve integral, surface integral and infinite series, so I don't take the exam.
