Union apprenticeship sign-ups near Tampa after 3 years as an accounts payable clerk

I heard of an apprenticeship with paid on-the-job training for people changing careers. 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 13 months ago, and it settled down once I kept a simple log of every call and form.
