PLEASE NOTE:  There is now a clear correlation between those who did well in the course to those who show up and learn in class.  Set aside "Chemistry" time in your busy schedule to study just this course.  Be consistent, keep up with your weekly work, and you will do well.

PLEASE NOTE:  There will be increased security at the exam sites.  Unlike high schools, UW does not tolerate academic misconduct.  If you get caught cheating, you will be expelled.  Don't do it!





Supplementary materials for the lectures will normally be loaded 24 hours before the lecture as we proceed.
Please check the table below.

EXAM INSTRUCTIONS Despite after Chem 120 and both term tests of Chem 123, there are still some students who don't want to follow the instructions on the exam in filling out the computer card and the exam paper.  In the final exam, the Chem 123 policy is that if the computer card and exam paper are not filled out according to the instructions (e.g. missing section number, missing name written in pen, missing id, etc), these will be thrown out and the student will get zero automatically on this exam.  There will be zero tolerance on this.  By now, we must learn how to follow the instructions, as there will no one there to bail us out from now on.  Please read and follow the instructions carefully.


The THREE Golden Rules in Writing Exam
(1)  Upon receiving the exam, write down what you know - your name, student id, test version number, course number, session number - This will calm your nerves as these are info you know you will get right!  And, this will allow you time to do the last-minute things at the end of the exam.
(2) In the first 5 minutes of the exam, scan over the complete exam once and identify the easy questions - This will allow your unconscious mind to work on the questions.  Select and do the easy questions first.
(3)  In the last 5 minutes of the exam, where applicable, cross out any junk that you have written down - This will help to clear your thought and to minimize infuriating the marker.  A messy paper obscures the real solutions - even if you might have written the solution down somewhere, the marker usually gives up and marks the question wrong if  the answer cannot be found in the first 10 seconds.  On the other hand, a "neat" and logically presented paper always wins gravy points from the marker.
