The time for postgraduate entrance examination is 3 hours, namely 180 minutes. Mathematics for postgraduate entrance examination is divided into Mathematics I, Mathematics II and Mathematics III, and the mathematics subjects in different majors are different.

Choose to fill in the blanks in 40-60 minutes, not more than 60 minutes; It takes 80- 120 minutes to solve the problem, and it cannot exceed 120 minutes. Students with sufficient ability can complete the exam in 120 minutes (40+80 minutes), leaving 60 minutes for the exam; Most people don't need to leave inspection time, and 180 minutes (60+ 120) is also acceptable.

Advanced algebra is the general term for the development of algebra to advanced stage. In detail, when discussing binary and ternary linear equations and studying quadratic equations or equations that can be reduced to quadratic equations, elementary algebra continues to develop in these two directions, and develops to the stage of discussing any number of unknown linear equations (also called linear equations) and studying higher-order unary equations, which is called higher algebra. Advanced algebra is the general name of algebra's development to the advanced stage, the necessary basic course for the application of mathematics in other disciplines, and the core course for mathematical cultivation. It includes many branches. Higher algebra offered by universities now generally includes two parts: linear algebra and polynomial algebra.
