The course of financial mathematics foundation is difficult to test. It is a class reorganized by some good students from the School of Economics and some good students from the School of Mathematics. To join this class, you must be a science student with high scores in mathematics and college entrance examination. If you are a candidate from Shandong and have reached the admission score of Mathematics College (about 645+), I suggest you apply to Mathematics College first, and then enter the basic class of financial mathematics from Mathematics College, which is easier to enter. If you are a candidate with a general education level in some provinces and have reached the admission score of the School of Economics, I suggest that you enter the basic class of financial mathematics from the School of Economics, which is more likely, because the selection method of the School of Economics avoids the competition of candidates from different provinces, to be precise, avoids those arrogant Shandong candidates.
As you said, this major is jointly organized by the School of Economics and the School of Mathematics. If you are a candidate this year, the financial mathematics class you want to enter is managed by Mathematics Institute. Come on anyway ~
