Apprenticeship openings for electricians and welders - what worked for you?

A local apprenticeship programme is taking applicants for the next intake. This is my first time dealing with any of this. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. How hard is the test?

Bring your transcripts and any proof of work history. They asked for both in the interview.

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