Union apprenticeship sign-ups near Portland - 13 weeks in

I heard of an apprenticeship with paid on-the-job training for people changing careers. I do not usually post, so bear with me. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. How hard is the test?

Bring your transcripts and any proof of work history. They asked for both in the interview.

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