Apprenticeship openings for electricians and welders - 5 weeks in

I heard of an apprenticeship with paid on-the-job training for people changing careers. I have read a lot of threads here and could not find my exact situation. Classes are in the evening and work is during the day. What do you wish you had known?

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.
