Union apprenticeship sign-ups near Wichita, store manager here

A local apprenticeship programme is taking applicants for the next intake. This is my first time dealing with any of this. Applications close in 13 weeks. What do you wish you had known?

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

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