Requirements
The following items count towards your course grade:

Refer to each page for a discussion of specific requirements and more information. You must respect the Code of Academic Integrity for all work!

Core vs Bonus Points
There are 2 kinds of points that you can earn for completing course work:

core: all required points for graded work

bonus: points that exceed assignment/exam requirements

You can receive bonus points that can improve your course grade from the following sources:

Some exercises, projects, and exams might award bonus points for additional and/or exemplary work.

Remaining points from dropped assignments and exams will contribute to your bonus points.

How do bonus points work?

We will scale bonus points from these sources after determining your letter grade based on your raw numerical score.

We do not consider bonus points until after assigning all letter grades so that we avoid distorting the class curve.

Bonus points can raise your letter grade about a third of a grade, e.g., C+ to B- but not C+ to B.

So, doing extra work always help you learn, but never causes competition with fellow students.

(Raw Numerical) Course Score Computation
We calculate your (raw numerical) course score based on core points for assignments and exams. The weights are as follows:

E	= Exercises and Quizzes	`: 10%`
P	= Projects	`: 20%`
T1	= Prelim 1	`: 10%`
T2	= Prelim 2	`: 20%`
T3	= Prelim 3	`: 20%`
T4	= Final	`: 30%`
DROP	= Lowest Score	`: -10%`
	= min(E,P,T1,T2,T3,T4)

Therefore, your (raw numerical) course score has the following formula:

Course Score = .1*E + .2*P + .1*T1 + .2*T2 + .2*T3 + .3*T4 - .1*DROP

We (partially) drop your lowest score DROP using the min operation, as shown above.

Example: Given the following averages in terms of percentages E=95, P=85, T1=78, T2=80, T3=92, F=87 the student would receive a course score of 86.5. In this example, Prelim 1 has the lowest score. Since Prelim 1 is worth only 10%, its score is dropped entirely in this example.

Note: CS100J has a slightly different grading structure:

Exercises and Quizzes count 5%, not 10%.

Projects count 25%, not 20%.

Only tests are dropped: DROP = min(T1,T2,T3,T4), with P and E excluded.

Letter Grades
We base letter grades upon the overall distribution of (raw numerical) course scores. After assigning your letter grade, we will raise your grade if you have earned sufficient bonus points, as discussed above. Further, we reserve the right to make adjustments both up and down based on our knowledge of each student.

Regrades
If you feel that the graders have incorrectly graded an exam or assignment, you must:

Go to Carpenter Lab.

Fill out a regrade request form.

Attach the exam or assignment to the form.

Submit the regrade request to a consultant in Carpenter.

Please note the CS100 policies:

We photocopy a random number of exams after grading.

You must submit your request within one week after we return your graded work.

We regrade the entire submission from scratch.

Your grade may go up or down.

You can retrieve the regraded material in Carpenter about 1 week after you submit your request.

Online Grades ( Core Exercise Scores | Core Project Scores | Exam Scores and Course Grades )

Grades are posted online, protected by the same password used for your online submission account. It is your responsibility to verify that our records are correct. If you find an error, please contact the course administrator, Laurie Buck, during her office hours.

Note:

Each exercise is worth 1 core point except for E4 (0 core points) and E9 (2 core points).

Overall exercise score E is computed by adding all exercise core points and dividing by 12 (about 3 exercises are dropped).

Each project is worth 10 core points (sum of correctness and style points) except for P7 (5 core points).

Overall project score P is computed by adding all project core points and dividing by 50 (about 1.5 projects are dropped).

Test scores are converted to percentages in the formula above. (T1/105, T2/105, T3/90, T4/170.)

Incompletes
We do not give incompletes, except in cases of severe problems, like debilitating illness and death. All cases are handled by the course instructor.
