The difference between one, two and three in mathematics for postgraduate entrance examination mainly lies in the content and object of examination. Let's look at it separately.

Judging from the content of the exam:

Mathematics 1: 60% advanced mathematics +20% linear algebra +20% probability theory and mathematical statistics.

Math II: 80% Advanced Mathematics +20% Linear Algebra

Mathematics III: 60% advanced mathematics +20% linear algebra +20% probability theory and mathematical statistics.

From the inspection object:

Mathematics one exam object: master of science and engineering

Mathematics 2 exam objects: agronomy, science and engineering.

Three subjects of mathematics examination: economics and management.

Difficulty: Generally speaking, there is little difference between Math 1 Difficult Math 2 and Math 3, but many people think that Math 2 is difficult to Math 3, depending on the annual examination.

I hope everyone can get satisfactory results in Math I, Math II and Math III.
