Trades apprenticeship applications open in Sacramento - any advice?

A local apprenticeship programme is taking applicants for the next intake. This is my first time dealing with any of this. Applications close in 25 weeks. What do you wish you had known?

Visit the training centre in person if you can. Seeing the classrooms helped me decide.

Thanks for writing this out. I went through something close to it 5 months ago, and it settled down once I kept a simple log of every call and form.
