Apprenticeship openings for electricians and welders - 10 months and counting

A local apprenticeship programme is taking applicants for the next intake. I would rather hear the honest version than the polite one. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. What do you wish you had known?

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

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