Union apprenticeship sign-ups near Austin - 16 weeks in

A local apprenticeship programme is taking applicants for the next intake. I do not usually post, so bear with me. The application needs a diploma or equivalent, a driver's licence and a short aptitude test. What do you wish you had known?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
