like others said, only do the class if you intend to actually do some work as an EMT-B. There are a lot of applicants that have the certification but don't do anything with it. Being an EMT-B will allow you to get some direct patient care experience, get some experience in assessment and physical examination, and even use some drugs, depending on the state (usually limited to oxygen, epinephrine (sometimes limited to use of an EpiPen), activated charcoal, nitroglycerin, albuterol sulfate, and glucose). Make sure you work with a group that you can actually go on calls and do patient care. Some will just limit you to driving or nursing home/hospital to nursing home transport. If you have a college group that's great too. After you get some experience you can also look into jobs as an ER tech, where you can do many of the things you do as an EMT-B, plus other technical skills, like starting IVs, blood draws, doing EKGs, different kinds of splints, nasogastric tubes (depends on the ER), arterial blood gas (also depends), being involved in codes, etc. It's all fun, but only if you REALLY want to do it, as it's all time consuming, and especially as a tech, you get to do all these interesting things (and SEE interesting things-my favorite), but you also have to do many other things that aren't always fun, like helping to clean up a patient or making beds. Once passed that, I guarantee that you'll see many things that'll make for conversation in interviews.
