How to get the tech 3 promotion

I've maid a few post in the past about getting the job and ask what I should I do as a tech two but I'm half way through my six months and I really want to know what I need to learn to become a tech 3

I want to know what training material I should buy or lookup

What troubleshooting I should know off the top of my head

All equipment and terminology

Finally how should I approach others in the facility

I work under a tech 3 but he's a older guy and did it himself that he's lazy so that's why I want to ask people in here who seem to want to do more.

Also I know I need to learn more about hydraulics and control cabinets that's my weakest area
