I have a job interview this week and I need to be more knowledgeable about the Affordable Care Acts, specifically the exchanges.

I have a degree in public policy and I was in school when the ACA was passed. Thus far it hasn't made a huge impact on my life other than that I'm under 26 and don't have to think about insurance at all (yay!).

I'm looking for videos, podcasts, written materials to catch up with and be able to have a better ACA-based conversation. Help?
