In the United States, the NEC (the code) allows emt to be used as your grounding conductor. But there are some requirements that make it impractical.
First, the fittings (couplings and connectors) must be listed for grounding purposes. As an electrician, I know that properly installed emt provides adequate grounding, but the code requires the fittings to be LISTED for the purpose, and I have never seen an UL listing stating this to be so.
You are also required to BOND boxes and devices such as receptacles and switches to the grounding conductor. Bonding the boxes cannot be done without properly listed connectors. Bonding devices can easily be done if you buy the right parts because some are manufactured for and listed as self-bonding.
What I am saying is this: Technically it is not necessary to run a ground wire inside emt. But other requirements of the code cannot be satisfied.
I would never do it on my own, but I might with clearance from my supervision and/or the inspecting jurisdiction. I was on a $300M government job that was designed, in its entirety, for the conduit to be used as grounding conductors. But as much as we discussed it and tried to make that happen, we couldn't satisfy the code.
In an EMT (Electrical Metalic Tubing) system the conduit system serves as the ground return. In some instances a ground wire also has to be installed in the conduit system along with the load wires.

You can attend either vocational or technical to become an EMT. The necessary training can be obtained in as little as 3 weeks. College is not required.
You can get your emt certification at www.nremt.org. Another good way to get the certification is through www.allalliedhealthschools.com/faqs/emt
EMT schools teach students everything necessary to become and Emergency Medical Technician. This includes caring for injuries or other emergency health issues such as heart attacks.

Yes, EMT training is so necessary, and required to stay qualified, in the colleges, but it's not considered a time consuming, as training through long time increase your skills.
Yes, it is necessary to attend school in order to become an EMT. I am not sure where you are located, but you can research the options in your area. You can also try taking the training online at education-portal dot com.
1" 1/2 EMT for 1/0 copper wire, or 2" for 3/0 Alum wire or copper clad Alum.
EMT is not a root.
To be an emergency medical technician you will be required to pass the necessary courses and the state license exam. Check with your state to see where you can take the test.
It depends from state to state, but most requires you to work a full year as an EMT Basic before you can become an EMT Paramedic. You need to take the EMT Paramedic training and certification.
