Trades apprenticeship applications open in Chicago - 6 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. How hard is the test?

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

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