My goals are to become a Paramedic, maybe go into law enforcement, and work in Emergency Management ( not sure where though).
Well personally I would tell you to try and narrow down those three things, and pick two. Some careers encompass two of those three items, however not many do all three, and I think it would be a waste of time to study in a field you aren't going to utilize in your future career.
For example: If you wanted to be a Paramedic and purse a career in law enforcement maybe a job like the Maryland State Police would be for you. You could be a State Trooper, and eventually transfer to aviation command and be a flight paramedic. However they don't do a lot of emergency management stuff unless you went into a branch like executive protection or something where you MIGHT do some emergency management/SOP work.
If you wanted to do LE and Emergency Management then there are a ton of opportunities with branches like the FBI, FEMA, Secret Service, Metro Transit, Capital Police, etc etc all of which have both of those components, but you will not utilize your Paramedic.
If your interested in being a medic and Emergency Management, maybe a position at a hospital ER doing emergency management would be up your alley.
In closing basically what I am saying is try to narrow your focus from three things to maybe the two that stick out to you of those choices. That will better allow you to focus your studies, time, and effort, and also search the job market ahead of time for positions you may be interested in. Good luck.
