Yup, most courses require 120-140 hours. When I took my course in NJ that came out to either 12 or 16 weeks...it was 5 years ago so I can't remember exactly. The course met two nights a week for four hours plus some Saturdays. I think that's fairly typical, and as others have said full-time or condensed courses are available as well. Good luck pursuing your certification! It's a great field, a lot of fun, and excellent preparation for further medical training. I feel my 3 years experience as an EMT gave me a real advantage compared to my medical school classmates in terms of being comfortable with patients, knowing the basics of a patient interview, etc. that's still benefiting me now as an MS2. It's a great thing to do as a pre-med. So good luck!
