Union apprenticeship sign-ups near Madison - what worked for you?

A local apprenticeship programme is taking applicants for the next intake. There are 14 people counting on me, so I am trying to be careful. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. What do you wish you had known?

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

Visit the training centre in person if you can. Seeing the classrooms helped me decide.
