Union apprenticeship sign-ups near Chicago (update)

The training centre near Chicago opened applications for apprenticeships in electrical and welding trades. I do not usually post, so bear with me. Classes are in the evening and work is during the day. Did anyone go through it?

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.
