The practice exams are the waiver exams from Fall 2008 and Fall 2009. There are some topics on the exams that we did not spend much time covering, like the weak axiom. Likewise, there are topics that were not fit for the waiver exams because of our idiosyncratic treatment but would be fit for the 14.121 final exams (i.e. robust comparative statics).
