ACM Tutoring
ACM Tutoring for lower division courses such as CS40 will be available this quarter on Mondays, 17:00--18:30; Harold Frank Hall 1152.
Grading
There will be 5 Homework assignments, 1 Midterm, and 1 Final. See "Course Schedule" below when these are scheduled during the quarter.
All questions of the HW Assignments, Midterm and Final will be graded using the following scale:
- 6 points: Exemplary; student applies knowledge with virtually no conceptual or procedural errors
- 4 points: Adequate; student applies knowledge with no significant conceptual errors and only minor procedural errors.
- 2 point: Minimal; student applies knowledge with occasional conceptual errors and only minor procedural errors.
- 0 points: Unsatisfactory; student makes significant conceptual and/or procedural errors when applying knowledge.
Your ultimate score for the course is determined as follows.
- The 5 Homeworks and 1 Midterm all count for an equal amount; the final counts for 2 Homeworks. This means that your total grade will be determined according to: 5 Homeworks + 1 Midterm + 1 Final = 5/8 + 1/8 + 2/8. In other words, each homework and midterms counts for 1/8th, the final counts for 2/8th.
- However, during the Final you are allowed to decide whether you want to drop your lowest score among your homeworks and midterms and let your final count for 3/8th, in which case the equality becomes: 4 Homeworks + 1 Midterm + 1 Final = 4/8 + 1/8 + 3/8 or 5 Homeworks + 0 Midterm + 1 Final = 5/8 + 0/8 + 3/8.
Means and Standard Deviations of HWs, MT, and F
The scores for the HWs, MT and F will be normalized before being added together. To calculate your 'normalized score', you take your score, subtract the mean, and divide by the standard deviation. The relevant means and standard deviations will be listed here as the quarter progresses.
- Homework 1 has mean 15.62, standard deviation 7.44, minimum 1, and maximum 24
- Homework 2 has mean 15.21, standard deviation 6.33, minimum 5, and maximum 24
- Homework 3 has mean 16.90, standard deviation 6.56, minimum 11, and maximum 24
- Homework 4 has mean 16.38, standard deviation 8.91, minimum 13, and maximum 24
- Homework 5 has mean 12.90, standard deviation 6.85, minimum 2, and maximum 20
- Midterm has mean 11.66, standard deviation 5.15, minimum 3, and maximum 20
As an example, if you scored 20 points for HW1, then your normalized score for HW1 is (20 - 15.62)/7.44 = 0.59. If you scored 9 points for HW2, then your normalized HW2 score is (9 - 15.21)/6.33 = -0.98.
Academic Honesty
The following applies to every course you attend at UC Santa Barbara (from UCSB Campus Regulations, Chapter VII: "Student Conduct and Discipline"):
It is expected that students attending the University of California understand and subscribe to the ideal of academic integrity, and are willing to bear individual responsibility for their work. Any work (written or otherwise) submitted to fulfill an academic requirement must represent a student’s original work. Any act of academic dishonesty, such as cheating or plagiarism, will subject a person to University disciplinary action. Using or attempting to use materials, information, study aids, or commercial “research” services not authorized by the instructor of the course constitutes cheating. Representing the words, ideas, or concepts of another person without appropriate attribution is plagiarism. Whenever another person’s written work is utilized, whether it be a single phrase or longer, quotation marks must be used and sources cited. Paraphrasing another’s work, i.e., borrowing the ideas or concepts and putting them into one’s “own” words, must also be acknowledged. Although a person’s state of mind and intention will be considered in determining the University response to an act of academic dishonesty, this in no way lessens the responsibility of the student.
Specifically for the current CS40 course this means that
- You are not allowed to copy or transcribe answers to homework assignments from others or other sources.
- Although you are allowed to discuss homework assignments with others, you should write down your answers independently. You should always be able to argue and explain your answers when asked for clarifications.
- During the Midterm and Final Examination no electronics are allowed, additional notes are only allowed to the extent described prior to the test.
- When you will be unable to hand in the homework in time you should report this to WvD as soon as possible, but always before the deadline. No matter the reason, you will always be asked to present documentation.
- When in doubt, ask.
- Students violating the rules of Academic Honesty will receive an "F" for the course and will be reported to the Dean of Students Office.
