Union apprenticeship sign-ups near Tulsa

A local apprenticeship programme is taking applicants for the next intake. I have read a lot of threads here and could not find my exact situation. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. How hard is the test?

The aptitude test was mostly maths and reading a diagram. Free practice tests online were enough for me.

You earn while you learn, but the first year is tight. Plan your budget carefully.
