Practice Exams

We post these with a few caveats-

1) at least one question (on a Molumby exam) is keyed wrong

2) it is OLD, so some of the stuff (including Dr. Molumby’s take on ecology, which is a little different than Dr. Murray’s) was not covered this year.

3) Please, don't ask us to post answers..experience has taught us that these are more effective when we do not.
