The difference between mathematics examination in subjects 1, 2 and 3:
1. Linear algebra: Mathematics I, II, and III all investigate linear algebra, accounting for 22% of the total. From the examination syllabus over the years, there is not much difference in the investigation of the linear algebra part of Mathematics I, II, and III, but the difference is that the vector space part of the knowledge is added to the syllabus of Mathematics I.
2. Probability theory and mathematical statistics: mathematical two are not examined, mathematical one and mathematical three both account for 22%, and mathematical one has more knowledge about interval estimation and hypothesis testing than mathematical three.
3. Advanced mathematics: Mathematics I, II, and III are all investigated, and they account for the largest proportion. The proportion of the first and third papers is 56%, and the proportion of the second papers is 78%.
