Trades apprenticeship applications open in Tucson - 5 months and counting

A local apprenticeship programme is taking applicants for the next intake. I have been trying to stay organised about it. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. What do you wish you had known?

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

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