Micro at Georgetown is very standard. The first semester covers everything but game theory, which is the focus of semester 2. Most people find it to be the hardest of the 3 first year courses, but if you are working through MWG on your own you are probably well prepared. I personally would have no chance of doing well while working full time, but everyone is different. Grading... professors seem to average us at a B+, which sounds high but we need a 3.5 to preserve funding. Getting a B+ is easy, getting an A is not. Hope this helps.
