mm,I couldn't find your original post on the other board, but here is a very good link.

It's MIT's open course website. the notes is the same as we used at school including reading assignments. There are lots of Economics courses, so you can choose which one you want to read. I am not sure if you ever read any econ. books, if not, I would suggest the basic Microeconomics-->Macroeconomics-->others. I don't think the graduate courses are that hard.

It's fun. Hope you enjoy it:)
