Nathan Koppel, One View on the Most Useful Courses in Law School (August 25, 2011):
Over at The Volokh Conspiracy [a blog], George Washington Law School professor Orin Kerr has written this useful item about a George Washington Law School survey that asked alumni which elective courses had proven the most useful to them and which electives they wish they had taken.
Here are the top 3 ranked courses on the usefulness scale:
1. evidence — (27% of respondents)
2. administrative law — (21%)
3. corporations — (18%)
