just a quick one seeking advice on which course to take:
I'm currently doing a few modules from a distance learning university's maths course to gain some solid maths qualifications.

I have completed the first course which is essentially a recap of high school maths (basic calculus, trig, logs, series/sequences, complex numbers, matrices/vectors etc)

I can either take another foundational course or a second year course.
The foundational course has the following syllabus:
number theory, conics, geometric transformation, mathematical language and proof, further calc, differential equations, mechanics, eignvalues and eigenvecotrs, combinatorics

the 2nd year course has:
differential equations (1st order, 2nd order, systems of, PDE, nonlinear), multiple integrals, linear algebra, fourier series.

I come from an economics background, so the latter course seems more relevant. but im interested in dabbling in computer/data science, where things like number theory and combinatorics seem more relevant.

I can take both, but they're pretty expensive.
