European seeking Computer Science or Math

[MrPanda]

To get Upper Level Math for free (if you complete them at the trial period), you could do the Coursera SAS specialization, to get STA-399:

Calculus II you could get it from https://www.straighterline.com/online-co...lculus-ii/

Calculus I you could take I from https://learn.saylor.org/course/MA005 for USD$ 5

You can take Discrete Mathematics at Study.com.

But if you are completing courses with Sophia, you could also do Calculus I there.

Just now I noticed that you said "RA credits", I have used Euroinnova/Nebrija (BUS), Escuela de Empresa/Nebrija (CS), Tech Universidad Tecnológica de México (There´s some math).

Maybe this one could work for the math degree:
