Kaiser has a quiz on some very good questions about the Medicare program. I only scored 50% on it, which surprised me. This is an excellent tool to educate the public about Medicare and the impact of the ACA.
see also http://tinyurl.com/8xwgdrc for my most useful blog entries. There are some very valuable postings.
fyi, this page has had over 800 hits since first posted indicating that folks are finding it very informative.
