I am a math major myself. Generally speaking, economics majors don't need to study mathematical analysis. If I study it, it's usually a little shallow.

Mathematical Analysis has two volumes, from the limit of series to multiple integrals. I don't know what stage you have learned. If you have studied multiple integrals, you should say that you have basically studied fractions.

Junior math classes include numerical analysis, operational research, even mathematical models and ordinary differential equations. These math departments must be studied, and most of the financial majors must be studied, but the degree is not as difficult as that of the math department.
