I took a First Aid course at a community college. It cost about $100 for the course. We met once a week and after the course was finished, we took a test and got certified for Red Cross (They give us a little card that says we are certified).
I then took an accelerated Emergency Medical Technician (EMT) course and that costed $500 for 1 month. We met monday through thursday from 3-10. We had to take the county EMT-I Basic test, now national registry or whatever and that costed around $45 (I forgot). Although it was long, it was an interesting and fun course.
To answer the OP's question, it was emergency first aid and it was for personal interest.
