Apprenticeship openings for electricians and welders, payroll clerk here

A local apprenticeship programme is taking applicants for the next intake. It has been weighing on me all week. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. How hard is the test?

Thanks for writing this out. I went through something close to it 11 months ago, and it settled down once I kept a simple log of every call and form.
