Up to 5 unannounced quizzes at 5 pts. each may be given in class.Total 600 pts.For each exam you should bring several pencils and your calculator. You may also bring and usea 3" by 5" note card containing any information you wish.Please note that 30% of your grade is based on homework. Homework may be discussed ingroups and with the GSIs and Professors. However, each student must turn in an independentcompleted assignment and should be prepared to defend all responses orally. Homeworkassignments are due in class on the dates listed. Late assignments will be docked 5 pts. per hour. If you are going to have a problem meeting a deadline for a justifiable reason talk to a GSI orProfessor before the assignment is due. No excuses will be accepted after the due date.Chem 260 Chemical Principles Winter 2001Outline for the First Exam Period:I.

The GSIs may deduct points forproblem sets that are messy and difficult to follow. We will not be checking significant figuresrigorously, but answers that retain several insignificant figures or omit several significant figureswill be considered incorrect. Note that an explanation of your answer may also be necessary. Several sample problems are given on the next
