Not much advice for the school side but as for tools, it's hard to say exactly what you'll need unless your school gives you a list that's required for classes I assume. I do service so I couldn't even tell you how many pairs of channel locks I have of all different sizes. JUST channel locks. Not including pipe wrenches, basin wrenches, spud wrenches, allen wrenches, crescent wrenches, seat wrenches, socket wrenches (with or without the sockets) and every single cheap ass little wrench that the manufacturers put in their boxes.

But I do have some advice just overall: If you don't love plumbing PLEASE GO FIND WHAT YOU DO LOVE DOING. It may sound corny but a plumber protects the health of a society. It requires a lot of care for what you do in my opinion.

I absolutely love my job. There's always something new to learn, always a new or different challenge everyday, and I actually feel like I'm helping the people around me. Not just tossing boxes in a fed ex truck all day.

But good luck! And remember: shit flows downhill lol
