MICRO 130 STUDY GUIDE

SAMPLE FIRST EXAM This should give you a pretty good idea of the types of questions I like to pose. Hopefully you will discuss and analyze them with other students in the class. If you're really stuck in trying to come up with an answer, call me (734-9123) or e-mail me (johnb@hawaii.edu) and I will get back to you.

Some questions refer to figures which unfortunately haven't been placed into this document yet. In most cases I believe that the context of the question will inform you about the facts and ideas you could be tested on. If you do want to see the figure, the exam on reserve in the library has the diagrams - but the questions are not in the same order as they are here.
