Your not wasting your time.
I joined the military out of high school, got out after 11 years and started emt all over again. at the time Michigan did not acept NREMT-B.
I was a SAR Medic. Flew Combat SAR with the USMC/USN
Got out, No one gave a :censored::censored::censored::censored...
I agree with above post.
In our profession alot of people talk the talk- but cant walk the walk.
IE they talk like they know everything- then on scene they dont have a clue,
or freeze or run around like a chicken with its head cut off.
Dont act like you know everything- actions speak just...
Dont quit.
hang in there, take the practice tests in a store book NREMT-B, go buy it
or there are sites to practice on the web. Some people do poor on written
tests. I failed ACLS the first time. Felt as dumb as a box of rocks. Good luck.
