I would recommend Econ 1B03 and 1BB3.
In my first year, I took Anthro 1A03 and Econ 1B03 (out of interest). I learned that Social Science is not my thing as they have to write papers supporting their argument by researching scholarly sources. In my own opinion, I'd rather sit for hours working on problems than to find citations to support my arguments.
But that's just me.
*edit*
Looks like Matthew and I submitted around the same time, there you have it!
