Exam Syllabus

The three part examination will be given in the context of CS 692, and this is the only mandatory aspect of the course. The offerings will be Fall and Spring semesters. On each part, a student must choose to answer 2 of 3 questions. One and a half hours are allotted for each exam. The exams are closed book, closed notes.

    Section 1: OPERATING SYSTEMS (1.5 hours - answer 2 out of 3 questions)

    Section 2: ADVANCED ALGORITHMS (1.5 hours - answer 2 out of 3 questions)

    Section 3: THEORY OF COMPUTATION (1.5 hours - answer 2 out of 3 questions)

The 3 questions on each test may come from anywhere in the respective syllabus.

The course grade is based solely on the exam scores and results in CREDIT/NO CREDIT for the course.   The student will complete 2 questions on each test, where each question is worth 20 points. The student must pass each test individually, with a score of 24/40 (60% rule) or better.   If the student passes all 3 tests, they will receive a CREDIT (PASS) grade.   If the student does not pass all 3 tests, a NO CREDIT grade will be issued.   In this case, the student should contact the graduate coordinator about re-taking the exam.

The following is the standardized Student Learning Outcome (SLO) for each exam:

Grading
Result Grade Student Learning Outcome
Excellent 35-40 pts : Understands essentially correct solution
Good 29-34 pts : Understands correct solution, but some errors in execution
Passing 24-28 pts : Some understanding of solution, but has errors
Poor 13-21 pts : No understanding of solution, but has some knowledge of topic area
No Effort 0-12 pts : No understanding of the solution, or the topic area

The above descriptions are on a per answer basis, and do not account for the variety between the two selected problems in the section. For example, scores of 17 and 17 are both essentially correct and yield an overall Excellent (34) result. Another example is an Adequate (22) result derived from an Excellent (17) understanding of one problem but No Effort (5) on the other problem.
