As a reminder: Final-exam regrade requests can be submitted until the end of this week.
Thanks everyone for a great semester!
Please note that travel constraints do not qualify as "extenuating circumstances"; the time and date of the final exam were announced on the course web site in August. (Also, because the exam is online, you should be able to take it from wherever you are, unless you are actually in the air Wendesday morning.)
The final exam (both regular and conflict) will be offered online with Zoom proctoring, Just like Midterms 1 and 2. To stay within the 3-hour time window allocated for finals, students without time accommodations will have 2½ hours to take the exam, plus 30 minutes to scan and upload.
Regrade requests can be submitted until two weeks from today: Monday, December 13.)
Here is the distribution of midterm grades and computed course averages. The orange curve shows computed course averages (36% Homeworks 1–9 and GPS 1–10 + 64% Midterms 1 and 2) for all students who took both regular exams, sorted in decresaing order. These averages were used to define the vertical letter-grade boundaries. The blue dots show the sum of both midterm scores for each student. Dots that are further above the orange curve indicate students with lower homework averages. Notice that the vertical scales do not have the same range.
Assuming a HW+GPS average of 90% (the class median), a total midterm score of at least 82 is consistent with an A, a total midterm score between 58 and 81 is consistent with a B, and a total midterm score between 35 and 58 is consistent with a C.
Please keep in mind that this is an extremely rough prediction of your final course grades, based on roughly 60% of the overall work. In particular, these estimates were computed without dropping any homework or GPS scores, so they should be considered slightly conservative. Past experience suggests that most students‘ final course grades will be within half a letter grade of these estimates, but differences of a full letter grade (in either direction) are quite common every semester.
Here is a scatterplot showing Midterm 1 scores (x-axis) versus Midterm 2 scores (y-axis):
The orange curve shows computed course averages (36% Homeworks 1–4 and GPS 1–4 + 64% Midterm 1) for all students who took the regular exam, in sorted order. These averages were used to define the vertical letter-grade boundaries. The blue dots show the corresponding midterm scores for each student. Dots that are further above the orange curve indicate students with lower homework averages. Assuming a HW+GPS average of 95% (the class median), a midterm score of at least 40 is consistent with an A, a midterm score between 28 and 40 is consistent with a B, and a midterm score between 16 and 28 is consistent with a C.
Please keep in mind that this is an extremely rough prediction of your final course grades, based on roughly 30% of the overall work. Past experience suggests that most students‘ final course grades will be within one letter grade of these estimates, but differences of a full letter grade (in either direction) are quite common, and there are a few differences of two letter grades or more (in either directions) every semester.
Students are strongly encouraged to talk with Jeff or Dakshita before dropping the class. In addition to his usual Friday office hours, Jeff will be available Friday 11-1 and 3-5, specifically for students who are thinking of dropping the class and/or are seriously concerned about their midterm performance.
All students are encouraged to answer each other's questions directly in Discord, or to upvote (via reactions) questions they woudl like the lecturer to answer. Another member of the course staff will monitor Discord form the lectuer hall, answer simple questions directly, and forward interesting/upvoted questions to the lecturer. All Discord questions and answers will remain on that day's lecture channel through the end of the semester.
