Union apprenticeship sign-ups near Omaha - first time posting

I heard of an apprenticeship with paid on-the-job training for people changing careers. There are 8 people counting on me, so I am trying to be careful. Applications close in 21 weeks. How hard is the test?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
