Sigh, here we go again.
Tell you what, you have so many questions about being an EMT, why don't you go to the Hospital and discuss their education program and EMS system with them. Coming in here and asking us about it is a waste of your time because you have practitioners in here from all over the world and you haven't even narrowed down what country you're asking about let alone a specific region. The answers you've already gotten here are all over the map and haven't solved anything for you, and now, when people start providing some constructive criticism you get all pouty and defensive.
That crap don't float here boy. You're obviously only about 15 or 16 years old and interested in this as a career, we get it, but if you want to be treated with respect you're going to have to earn it, because we see guys like you come and go around here all the time. The option is yours, choose to learn from the people here who are actually trying to help you and taking time from their lives to answer your questions to the best of their ability, not pick at you, or go hang out at EMTlife.com.
He's all yours Mike.
