First figure your homework grade. Your HW percentage is your total number of HW points divided by the number of HW points which are possible. There are about 3300 possible HW points for the entire semester. However, we will figure the final HW percentage out of only 2970 points (or about 90% of all possible points should the number of possible points change). Your WebAssign "All Assignments" link gives you your total WebAssign points for each of the Homework Assignments for the year. The total number of HW points is your total number of WebAssign HW points for the semester. To this total, you must add the points earned in the two Extra Credit Opportunities of the semester. This is done for you in our HW grades page. As an example, say you have earned 2538.6 WebAssign points, and you participated in one Extra Credit Opportunity, for which you received 75 points. Your total HW points for the semester would then be 2538.6 + 75.0 = 2613.6. With 2613.6 HW points for the semester your HW percentage would be: 2613.6/2970 = 88.0% HW is worth 14 points overall, so you would have earned 12.32 HW points (i.e. 88.0% of 14). The maximum HW score is 100%, i.e. 14.0 points. 1300 HOMEWORK POINTS ARE REQUIRED FOR A PASSING GRADE IN THE COURSE. LESS THAN 1300 HOMEWORK POINTS IS AN AUTOMATIC E. Now figure your Turning Point grade. There are expected to be about 95 Turning Point questions over the course of the semester, so the maximum possible Turning Point score will be about 285 points. The final Turning Point grade will be determined as a percentage out of about 255 points (or about 90% of all possible TP points should the number of possible TP points change). Say you have earned 212 Turning Point points for the semester. Your Turning Point percentage would then be 212/255 = 83.1%. Turning Point is worth 5 points overall, so your TP points for the semester are 4.16 (83.1% of 5). OK, now figure your recitation grades. We grade quizzes out of 25 points and we give half-weighting to the worst of your 3 quizzes. Say your 3 quiz scores are 22, 15, and 18. Your Quiz Average is then (22*2 + 15*1 + 18*2)/(5*25) = 95/125 = 76.0%. Quizzes are worth 6.0 points total, so your Quiz points for the semester are 4.56 (76.0% of 6). We grade group exercises out of 10 points and we take your best 7 out of 9 group exercises (for WED recitations, we take the best 8 out of 10). Say your best 7 group exercises total up to 68 points. Your exercise average is then 68/70 or 97.1% (Students in WED recitations divide the total of their best 8 exercises by 80.) Exercises are worth 5.0 points total, so your Exercise points for the semester are 4.86 (97.1% of 5). Now figure your test total. We grade tests out of 15 points and we give half-weighting to the worst of your 3 tests. For example, say your MC test grades are 10.0, 13.5, and 8.5. Your test average is then (10.0*2 + 13.5*2 + 8.5*1)/(5*15) = 55.5/75 = 74.0% We now multiply by 50 since the Tests are worth 50 points overall. 0.740 times 50 = 37.0 OK, now you have your pre-exam total. HW 12.32 TP 4.16 Exercise 4.86 QUIZ 4.56 TEST 37.00 ------- pre-exam total 62.90 The pre-exam maximum is 80 points, so your pre-exam percentage is 62.90/80 = 78.63% The final exam is 40 MC questions and counts for 20 points in your overall average. Your final exam score is simply the number correct, out of 40; therefore, you only need to add half of your final exam score to your pre-exam total to get your overall total score. For example, if you score 30/40 on the Final Exam, you would add 15 points to your pre-exam total to get your overall average. pre-exam total 62.90 points exam score 30/40 15.00 exam points ------- average with exam 77.90 points overall Any student who earns 80% of all possible points can expect to receive an A of some type (A-, A, or A+); students who earn 65-80% of all possible points can expect to receive some type of B, and students who earn 50-65% of all possible points can expect to receive a C or C+. The letter grade cutoffs may be lower than those posted here, but are unlikely to be higher. At the end of the semester, see the Final Histogram on our Overall Grades page to see where the final plus-minus cutoffs lie. Thanks. GBA
