This is the week of Midterm Exam #1. It covers Chapters 13 and 14 from our textbook (essentially problem sets 1, 2 and 3); look at the materials below for more information. The following week (week 6) is Class Presentations week, so start getting ready for that as well Let me know if you have any questions!

Here's what is happening in week 5 of CH 223:

• Midterm Exam I
  • This midterm exam covers problem sets #1, #2 and #3 (essentially Chapters 13 and 14 with a touch of Chapter 15.)
  • The midterm will have 20 multiple choice questions and four short answer questions. You will not need a scantron to complete the exam, but you will need to mark your answers clearly on the exam itself.
  • The first and last pages of the exam deserve some comment. The first page of the midterm will include an integrity statement that you will be required to sign. Signing the integrity statement implies that you have not received (and will not be giving) any information on the midterm exam to others that might imply cheating; a failure to sign the integrity statement grants an automatic score of zero, so make sure the first thing you do is to sign the statement. The last page of the midterm exam will be a scoring page which will be filled out by the instructor when the exam has been graded; you do not need to complete anything on this page. An example of the integrity statement and grading sheet can be found here.
