Apprenticeship openings for electricians and welders

The training centre near Denver opened applications for apprenticeships in electrical and welding trades. I do not usually post, so bear with me. Applications close in 7 weeks. What do you wish you had known?

Bring your transcripts and any proof of work history. They asked for both in the interview.

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