Trades apprenticeship applications open in Cleveland - any advice?

I heard of an apprenticeship with paid on-the-job training for people changing careers. There are 17 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. How hard is the test?

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.
