- GNS3
Grading
Projects, and Problem sets
-
Students are evaluated mainly by THREE exams and THREE projects (two in-class, one take-home).
-
A sample problem set will be given two weeks prior to each exam. Only first two problem sets will be graded, but it is highly recommended to use them for exam preparation.
-
A submission and passing grade of Individual Project 3 is required to get a pass grade.
| Item | % in Final Grade |
|---|---|
| Exam 1 | 20 % |
| Exam 2 | 20 % |
| Exam 3 | 20 % |
| Individual Project 1 | 7 % |

Late Submission
Late submissions within 24 hours will be deducted 10% of its final grade. Submissions over 24 hours late will have 20% grade deducted. Late submissions over 2 days will not be accepted.
Attendance
I do not take attendance except for the first two classes. Students not attending either of the first two classes will be dropped to make room for students on the waiting list. Attempting to get marked as present (by have someone else attend in your place or using technological deceptions) will be considered academic dishonesty and at a minimum will result in you getting dropped from the course.
Grading Policy
The University Policy S16-9, Course Syllabi (http://www.sjsu.edu/senate/docs/S16-9.pdf) requires the following language to be included in the syllabus:
“Success in this course is based on the expectation that students will spend, for each unit of credit, a minimum of 45 hours over the length of the course (normally three hours per unit per week) for instruction, preparation/studying, or course related activities, including but not limited to internships, labs, and clinical practica. Other course structures will have equivalent workload expectations as described in the syllabus.”
University Policies
Per University Policy S16-9, university-wide policy information relevant to all courses, such as academic integrity, accommodations, etc. will be available on Office of Graduate and Undergraduate Programs’ Syllabus Information web page at http://www.sjsu.edu/gup/syllabusinfo/. Make sure to review these policies and resources.
