The final Physics 1403 course grade is determined as follows:

1. Quiz Average: First, calculate your Quiz Average as a percentage. (I realize that I haven't returned many graded quizzes to you. I'm sorry. I'll have them graded & returned before our final exam). We've had 8 quizzes, each worth a maximum of 20 points. Call them Q1,Q2,Q3,Q4,Q5,Q6,Q7,Q8. So, a total of 160 quiz points were possible. There also were 15 extra points for sending an email when class began & 15 extra points if you signed the attendance sheet the class meeting just before Thanksgiving. These are added to the numerator when a quiz percentage is caculated, but not to the demnominator. Together, these are equivalent to 150% of an extra quiz! So, I do NOT drop the low quiz grade! Call the extra quiz points EP. So, it is possible to have a quiz % greater than 100% and some of you do! Call the Quiz Average Q. The Quiz Average Q (as a percentage) is thus calculated as:

Q = [(100)/(160)]*(Q1 + Q2 + Q3 + Q4 + Q5 + Q6 + Q7 + Q8 + EP)                                 (1)

2. Homework Average:
Next, calculate your Homework Average as a percentage. This should be available to you from Mastering Physics. We've had 15 homework sets, but the first one was for practice & doesn't count in your grade. Call the remaining 14 homework sets H1,H2,.......H14,H14. From the Syllabus, the Quiz Average is equal to one homework set.  The Homework Average H is thus calculated as:

H = [(1)/(15)]*(H1 + H2 + H3 + H4 + H5 + H6 + H7 + H8 + H9 + H10 + H11 + H12 + H13 + H14 + Q)   (2)

3. Lecture Average:
Next, calculate your Lecture Average. From the Syllabus, Homework H counts 20% of the lecture grade. We've had 3 Exams (call them EI, EII, EIII) PLUS the Final Exam (call it EF). The 3 Exams each count 20% & the Final Exam counts 40% (unless it is the lowest exam, in when it counts only 20%!) The lowest Exam (call it EL) of  EI, EII, EIII is dropped, OR the Final Exam counts only 20% if it is the lowest. So, the Lecture Average (call it L) is calculated as:

L = (0.2)*(H + EI + EII + EIII +  EF + EF- EL)                                                                  (3)

4. Lab Average:
I obtain your Lab Average (call it LA) as a percentage from your TA. 

5. Course Average:
Next, calculate your Course Average (call it G). From the Syllabus, Lecture L counts 80% of the course grade G & Lab LA counts 20%. So, the Course Average G is calculated as:

G = (0.8)*L + (0.2)*LA                                                                                                     (4)

6. Letter Grade: The Letter Grade given for the final grade numerical score G from Equation (4) will be according to the scale in the Syllabus:

100   >   A   >   90   >   B   >   78   >   C   >   66   >   D   >   54   >   F   >   0
