Suggestions? Sure:
1. Consider your age an advantage. You have life experience that should help you cope with the challenges ahead.
2. It certainly doesn't hurt to have significant experience as an AEMT, but don't make the mistake of assuming it's enough to get you through the program without working just as hard as everyone else.
3. Speak with your family about the obligations you'll have as a paramedic student and alert them to your more-limited availability. If they're not ok with that, do not pass Go.
4. You're going to face unpleasant clinical and social situations. Embrace the suck. A lot of what will seem crazy at first will become routine with practice.
5. When you have a week when stuff you thought you learned doesn't make sense anymore, and you wonder whether finishing the course is worthwhile, try helping a classmate who's in even worse shape.
6. Use actions, not words, to impress others with your abilities. No one will care about your AEMT war stories. Just be polite, reliable, and competent. That's usually enough.
7. Consider every patient an opportunity to demonstrate your competence, and every preceptor a potential employer.
8. Don't say anything bad about anyone, ever.
9. Don't fall behind on course material.
10. Don't plan vacations until after graduation.
11. Don't blame others for your troubles. Go back and try again.
