Sounds like you did a good job. I just finished my EMT-B classes and am awaiting test results from NREMT. I feel like I have probably forgot more than I ever knew but like you said, hopefully, it will come back to me when I need it.
Just a note about N2DFire's comment. In this area Medic is reserved for parmedics. EMT's like myself are refered to as EMT's
