Grades & Attendance
You may be interested in the distribution of course grades by class attendance (based on sign-in sheets) in PHYS 2212 K. The graph is showing that, for example, 62% of the students with "Good" attendance (greater than or equal to 90%) earned a A. The class GPA for students with Good attendance was 3.5. That for those with Fair attendance (60 to 90%) was 3.1, while that for those with Poor attendance (less than 60%) was 1.8. From another perspective, students with Good attendance were 41% of the class, yet they earned 52% of the A's. Student with Poor attendance were 18% of the class, but they earned 75% of the F's.

If you compare the above graph to the results for Fall 2008 through Summer 2010 posted at the beginning of the semester, you'll see that the trends are always the same! I'd like to thank those students who made the effort to attend class and participate.

Course Grades
Course Grades are available available in the Canvas PostEm Tool. If you think your grade is erroneous, please contact Dr. Murray. On the other hand, if you just wish your grade were different, please do not contact Dr. Murray! Grades are determined by the same standards for all students, and all possible consideration has already been given.

Final Exam Grades
Final Exam grades are available available in the Canvas Gradebook. Adjustments, similar to those on the quizzes, were made. Exam forms will not be released through Gradescope, although if you stop by his office, Dr. Murray will be happy to go over your exam with you. Contact Dr. Murray to schedule an appointment, or if you have any questions.

Final Exam Reminder
The final exam period has been set by the Registrar's Office. The Final Exam for PHYS 2212 K will be administered TOMORROW, Wednesday, July 31, 8:00–10:50am, in the same locations used for the quizzes. If any student goes to the wrong room, it is likely that there will be insufficient seats and/or quiz forms in that room!

• Family Names A–O - Boggs B5
• Family Names P–Z - Boggs B9

You may want to review the Exam Rules. Don't forget your photo ID.

The Final Exam will have three 16-point Free Response problems and sixteen 3¼-point Multiple-Choice questions. Some of the Multiple-Choice may require a bit more calculation than the Multiple-Choice did on the quizzes, but many will be strictly conceptual. I intend that topics in the course will be covered roughly evenly — that is, there will be no special emphasis on material after Quiz #3.

Remember that Quiz 5's from 2014 are available to help you prepare for material after Quiz #3.

Remember that calculators that cannot store text may be used on final exam. Note that if your calculator keypad includes a complete alphabet, that's a very good sign that it cannot be used. Do not expect to be provided with an appropriate calculator if you do not bring your own.

Remember the expectations for your work on the free response problems, which are the same good problem-solving practices you should be using on the homework, anyway.

• Units should be shown with any value that has a unit
• Algebraic manipulations should be performed with symbols, not values
• Consider, but do not obsess over, significant figures

You may find an example helpful.

Lab Averages
Final Lab Averages Lab Avg are available in the Canvas lecture Gradebook. Each student's poorest lab grade was dropped. If your lab grade seems surprisingly low, don't forget the penalty for excessive absences. Contact Dr. Murray if you think your posted Lab Average is in error.

Recitation averages
Final Recitation Averages Recit Avg are available in the Canvas lecture gradebook. Each student's poorest recitation grade was dropped. Contact Dr. Murray if you think your posted Recitation Average is in error.

"Other" Points
"Other" Points have been calculated and are available in the Canvas gradebook. Recall that "Other" consists of these items, the average for each of which is also in the Canvas gradebook:

	Weight in Course
Regular Homework	5+2%
Practice Homework	4%
Class Participation	4%
Reading Questions	2%

If you wish to verify the calculation,

1. If your Regular Homework average exceeds 100% due to working it on a daily, rather than weekly, basis, temporarily treat it as 100%
2. Multiply each component of the "other" grade by the weight above (with Regular Homework at 5%)
3. If the sum of those weighted components exceeds 10 points, discard the excess
4. If your Regular Homework average was 100% or less, this weighted sum should match the value in the Canvas Gradebook
5. If your Regular Homework average was more than 100%, divide the excess by 0.2 and add it to the weighted sum. For example, if your Regular homework average was 110%, the amount exceeding 100% is 10%, or 0.1. Then 0.1/0.2 = 0.5, so the value in the Canvas Gradebook should be 0.5 points greater than the weighted sum.

The greatest possible "other" score, therefore, is 12 out of 10. Contact Dr. Murray if you have any questions.

Quiz #3 Results
Results for Quiz #3 are available as a percent in the Canvas gradebook under Quiz #3.

The Gradescope link in the Canvas navigation menu will take you to Gradescope, where you will be able to see how you did on each Free Response problem and Multiple Choice question. Because the FR problems were graded as a percent, but the MC questions were graded as points, it was necessary to treat each student's quiz as if it were two quizzes in Gradescope, one with the FR problems and one with the MC questions. (The score posted in Canvas is your combined score.) Gradescope also shows you an internal code like ProbC d that is used to identify a particular question and its correct answer choice, despite the fact that it has a different question number on different versions of the quiz.

The Solution to the in-class Extra question has been posted.

If you wish to confirm your score in Cavas by your own calculation, consider first the four FR problems, three on the quiz and one Extra. The Extra problem didn't help as much as one might wish, so the four have been re-weighted like this: each student's best is worth 24 points, second best worth 16 points, third best 8 points, and the worst doesn't count at all. Find the points earned on each FR problem by multiplying the percentage score by the appropriate value, then add the points earned on all the MC questions other than ProbF. Divide the total by 0.92, add any points earned on ProbF, and add any points earned on the Extra qualitative question (energy supplied vs. stored). Scores may exceed 100%.

If you have questions or concerns about how your quiz was graded, you should contact Dr. Murray (the request regrade button in Gradescope is simplest, if that's your concern) before Monday, July 29.

Reading Day Study Session
The Center for Academic Success is hosting a two-hour Intro Physics Study Session at 10am on Reading Day, Thursday, July 25, in Clough 152. Try the Worksheet ahead of time!

Extra Credit
Extra credit for the Diagnostic and Concept Tests has been calculated and is available in the Canvas gradebook as "XC Points". If you wish to verify the calculation, divide the sum of your points by 128 (each had 32 points, for a maximum total of 64, so dividing by 128 yields a value betwen zero and 0.5). Then add 0.25 for each one you earned a score greater than zero on. The resulting total, between zero and one point, will be added to your course average.

In-Class Averages
Final In-Class (Reading Question "RQ Avg" and Class Participation "CP Avg") Averages are available in the Canvas gradebook. Contact Dr. Murray if you think your posted In-Class Averages are in error.
