Union apprenticeship sign-ups near Little Rock - what worked for you?

The training centre near Little Rock opened applications for apprenticeships in electrical and welding trades. This is my first time dealing with any of this. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. Did anyone go through it?

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.
