Union apprenticeship sign-ups near Knoxville - first time posting

The training centre near Knoxville opened applications for apprenticeships in electrical and welding trades. Classes are in the evening and work is during the day. Did anyone go through it?

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 11 months ago, and it got easier once I kept a simple log of every call and form.
