Grading: The total score for the course is computed with the following weights:
Online quizzes | 40% | Project reports | 8% |
Final Exam | 30% | Online homework | 10% |
In-lecture iClickers | 4% | Discussion worksheets | 8% |
Final grades: The total score s corresponds to final grades as follows.
97.0% ≤ s < 100.0% | A+ | 93.0% ≤ s < 97.0% | A | 90.0% ≤ s < 93.0% | A- |
87.0% ≤ s < 90.0% | B+ | 83.0% ≤ s < 87.0% | B | 80.0% ≤ s < 83.0% | B- |
77.0% ≤ s < 80.0% | C+ | 73.0% ≤ s < 77.0% | C | 70.0% ≤ s < 73.0% | C- |
67.0% ≤ s < 70.0% | D+ | 63.0% ≤ s < 67.0% | D | 60.0% ≤ s < 63.0% | D- |
s < 60.0% | F |
This means that a score of 79.998% is a C+, while 80.000% is a B-.
iClickers: Short quizzes are conducted during lectures using iClickers (70% participation, 30% correctness). An iClicker remote can be purchased from any of the bookstores, and must be registered on Compass, under the tab "Register i>clicker". You need to register your iClicker by the end of Week 2, when the iClicker roster will be synced for the last time. The first iClicker use for credit will take place in Lecture 2 of the semester. There will be 3 dropped iClicker grades.
Quizzes:These quizzes are designed to assess your problem solving skills on course material. Solutions will not be posted. All quizzes will be held in the CBTF (Computer-based Testing Facility) and follow the rules of the CBTF. Each quiz grade is determined from the following formula: max([First Try, 1/3*(First Try) + 2/3*(Quiz Retry)]).
Discussion sections: Discussion sections start in Week 1 of semester, with the schedule below. All discussion sections meet in MEB 252. Many of the doors to MEB are locked after 5:30pm, but the south entrance to MEB (i.e., facing Green St.) remains unlocked until 9:30pm.

Online forum (Piazza): This class uses Piazza for ALL communications between the instructor, TAs, CAs, and students. Students should not communicate with instructors via email. This is so we can ensure a faster response and keep everyone informed about what's going on.
Students are encouraged to post public messages on Piazza ("Post to Entire Class"). If you like, you can post anonymously, but we encourage everyone to use their name because it makes a friendlier and more welcoming environment. We will never judge anyone for asking anything on Piazza, and you will see professors, TAs, and CAs making mistakes and saying stupid things as well!
You can also use the private feature on Piazza by posting a message visible only to the Instructors. In this last case, you should type "Instructors", instead of sending a message to a specific TA or instructor. Again, this helps to ensure that you get a prompt response.
TAs and CAs are scheduled to be checking Piazza on the following days:
Sunday | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
