Union apprenticeship sign-ups near Columbus - first time posting

A local apprenticeship programme is taking applicants for the next intake. This is my first time dealing with any of this. Applications close in 2 weeks. How hard is the test?

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.

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