Union apprenticeship sign-ups near Jacksonville

The training centre near Jacksonville opened applications for apprenticeships in electrical and welding trades. I am in Jacksonville, in case local advice matters. Classes are in the evening and work is during the day. What do you wish you had known?

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.
