How difficult are these exams/practicals?

[ignition_point]

I just took my Firefighter1 exam/practical for Indiana, I challenged the exam and only missed 4 total, it was very difficult in my opinion. esecialy the practicals, out of the 101 possible skills, we we randomly assigned to the following four: Placing a roof ladder properly, putting on our PPE(gear), putting on an SCBA, and chaning the stream/gpm's on a nozzle. I kind of thought it was too easy. I also passed my Hazmat Ops course at the same time.

Anyhow, my real question is, how much more difficult is the FF2/Hazmat Tech. courses? My goal is to have, or at least begin, my Fire Officer 1 cert. by the end of the year, I'm just a junkie on training .
