Practice Exams

These are exams from the equivalent MIT course 8.022, from fall 2002, 2004 and 2006.

Solutions are available for the fall 2002 exam here (that course used a different system of units -- you can convert your answers to theirs by setting k=1 and epsilon0=1/(4pi)). I'll post comments about the problems on the exams continuously over the weekend.
