Apprenticeship openings for electricians and welders - first time posting

A local apprenticeship programme is taking applicants for the next intake. It has been weighing on me all week. Classes are in the evening and work is during the day. What do you wish you had known?

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

Thanks for writing this out. I went through something close to it 2 months ago, and it settled down once I kept a simple log of every call and form.
