Are you talking about paying to go to a school like North West Line? Or have you been accepted by an employer and going to their school? Where I was before I retired, you were accepted after passing a rigorous climbing test then accepted at a affiliated college. The college curriculum includes math, you’ll graduate with a 2 year degree. While you attend college, you’ll also attend Line school at the company.
