Should I Quit my current job?

Today I took my aptitude test and passed & accepted an offer for a pre-apprenticeship. Right now Im making ) $15 and getting roughly 30-35 hours a week. The pre-apprenticeship is $13 and I was given a clear yes or no to if it was full time or not. However I would be leaving monday and be gone till thursday and I think this is a weekly thing for the summer.

I wanted to give my current job a two weeks notice so that I can be on good terms with them but my IBEW interviewer told me that this is something they’re looking to fill immediately and that I should think about my future career rather than my current job. Should I leave my current retail job cold turkey?

The opportunity sounds promising and a good way to get experience but Im unsure of what to do.
