I became licensed in Health & Accident only in PA almost three years ago. That's all I needed to work in a call center that sold MA
/Med Supps and PDPs. They paid for the required 24 hour training, which was taught by an-onsite instructor. We actually had 40 hours of training, then I studied every night at home for about two hours and another week on my own. I passed with an 84% on the first try.
Once I started working on the sales floor, I quickly learned from other agents that if I wanted to do anything besides work there I needed to add Life. So I bought an online course from ExamFX, studied for hours a day until I was bleary-eyed and passed by the skin of my teeth with a 71%. The annuities just about killed me!
I have since recently obtained my Viatical Broker license (no testing required in my state if your Life license is 1-year + old) and currently studying for the P&C exam.
