In-class Participation (“clickers”):  2-6 clicker questions per lecture, some marked for participation only, some for accuracy as well.  (2% for participation on 80% of all questions, 1% for correct answer on 80% of accuracy questions - 20% grace)

Problem Sets:  5 of 6 problem sets, due one week after they are assigned (1% each)

Exams:  2 Midterms (Fri., October 3 and Wed., November 5) and Final (tba)

Calculator for Exams: You will need the standard UBC Science calculator (Sharp EL-510R or EL-510RN(B)), sold in the computer shop at the UBC bookstore, if you wish to use a calculator for any of your exams.

Grading:  In-class clickers 3%; Problem Sets 5% (best 5 of 6); Midterms 20% each; Final - 52%.  (Or 55% for final, 0% for clickers – whichever gives you the best result)
