Actually I am no longer fire as I disagree with how fire deals with EMS in the majority of city's. For a person to excel they need to specialize. If the fire department will let you "just" be a Paramedic in the good sense that you only work on the ambulance then you might be ok. If you have to rotate fire and EMS then you become distracted and often we find sub par patient care and very limited protocols which harms patients, basically you become a taxi driver as you are not allowed to perform hardly any medical interventions.
I hope you did not spend thousands of dollars for an EMT-B certification unless it was part of a college degree. There are 2 week courses for EMT-B as it is just a hair above a standard first aid class.
While waiting to enter Paramedic degree program go ahead and take college level A&P 1&2, microbiology, and other pre med courses to get you prepared.
Bite me.
