I am an undergrad student switching from actuarial science to mathematics. Currently i am taking advanced calculus (up to surface integrals and Stoke's theorem), discrete math, partial differential equations and statistical inference.

The mandatory courses include real analysis, abstract algebra, complex analysis and numerical analysis.

There are 2 numerical analysis classes:

Numerical Methods (More abstract with less use of Matlab or similar packages): Number systems and errors. Solution of nonlinear equations. Interpolation. Systems of linear equations. Approximation. Differentiation and integration. Solution of ordinary differential equations.

Engineering Analysis and Computation I: Solution of sets of linear equations, roots of equations, curve fitting (interpolation), numerical integration and differentiation, numerical solution of ordinary and partial differential equations, boundary value problems and introduction to the finite difference method of computer programs for problem solving. It includes a programming based project.

Any of both courses can fulfill the numerical methods requirement. (since the abstract one is rarely offered.) It seems that the less abstract version can be more beneficial since it includes intensive use of Matlab and it includes numerical solutions to ODEs/PDEs. What do you think?

In addition, I would like to seek your advice regarding some courses which can be relevant to or useful in finance/economics. (directly or indirectly even if its sole point of relevance is advancing the level of mathematical maturity and shaping an abstract mindset)

Kindly sort down the following courses in order (1 being the most relevant and useful and n being the least relevant) and explain the reasoning behind what you type down (if possible):

Artificial Intelligence

Introduction to Artificial Neural Networks

Grad Level Data Mining/ Machine Learning

I intended in the beginning to declare business but I found that an undergrad business degree is not that rigorous and that it is mostly useless since it includes skills and intuition based topics that requires professional training rather than undergrad academic training from my point of view (an exception can be the finance classes but even the finance classes are not rigorous)

i decided to switch to actuarial science and I passed 2 of the society of Actuaries exams; P and FM, but I found that I am less interested in working in the insurance industry and I didn't want to waste my undergrad years taking too applied courses like life contingency and insurance models so I decided to switch to mathematics. (even if for those who continue to work as actuaries, a math degree is better than an undergrad actuarial science degree because actuarial science is all about professional exams)

Regarding my academic career path, I intend to apply for either a Ph.D in economics or to further advance my computational skills through applying for a computational sciences masters program. Professionally, I am still not sure but I intend to work in something quantitative/computational in the financial industry.
