Apprenticeship openings for electricians and welders

I heard of an apprenticeship with paid on-the-job training for people changing careers. It has been weighing on me all week. Applications close in 6 weeks. How hard is the test?

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

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