Lao Lu's book clearly divides the modules. Although it seems that mathematics has many parts, after learning and summarizing, many logics are interconnected. Lao Lu's formal logic can be said to be the best of all institutions, simple and easy to understand, just like formulas, and can be mastered soon.

Logic seems to be irregular, and many people are dizzy after reading the problem, but in fact, logic is like a math problem, with its own laws and deductions. As long as the logical problem-solving ability is formed, the stem is no longer a lot of words, but a reasoning connected by A, B and C.

Lao Lu's advantage is that he is concise and systematic, and he will give you his fastest problem-solving skills. He won't bother you, teach you exams and give you a clear framework for managing mathematics. If you have enough training, you can do your own problems and quickly respond to the methods. The test center covers all, but it is not the most comprehensive, but it is enough compared with some colleagues who have to focus on Protestant trigonometry in the market.
