HOW DID YOU DO??
Don't like how you did the first time? Study the material again, then re-take the exam. Remember, vocabulary words are defined in the lecture notes glossary; figures and tables in the text can be a really good summary of processes, and your CD-rom and book have practice questions as well!!! Remember, do not wait for the exam to find out you really don't understand something - ask me a question if you are unclear about things. There is no such thing as a "bad" question but there is such thing as a bad exam grade! Reach me by e-mail (email@example.com), phone (278-4551), or in person (SL 330).
