Trades apprenticeship applications open in Knoxville

The training centre near Knoxville opened applications for apprenticeships in electrical and welding trades. 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 10 months ago, and it got easier once I kept a simple log of every call and form.
