Trades apprenticeship applications open in Tulsa

I heard of an apprenticeship with paid on-the-job training for people changing careers. I do not usually post, so bear with me. Classes are in the evening and work is during the day. How hard is the test?

Keep everything in writing and save the confirmation numbers. It saved me later.

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