The following is a repeat from the first test.

Don't leave any questions blank. Remember, partial credit is better than no credit at all.
On the short-answer and mini-essay questions, I will give you credit for giving me a CORRECT and COMPLETE answer, but not necessarily for a LONG answer. Remember, brevity is golden.
Always answer the bonus question. You're not going to lose any points even if you get it wrong, and I get a big kick from reading your answers.
