You are encouraged to do the labs within the lab hours, but you may access the labs at other times.
Be respectful of the other lab students and equipment at all times.
BE109 is available for working on matlab also. 

Grading Policy
Course grade will be based on weekly homework assignments and quizzes (25% of the final grade),
midterm examination (35% of the figrade) and a fi nal examination (40% of the fi nal
grade). You must get a passing grade on the final to pass the course. The final examination
will cover the material from the entire course.

Academic Dishonesty
Any confi rmed academic dishonesty including but not limited to copying homeworks or
cheating on exams, will result in a no-pass or failing grade. You are encouraged to read the
campus policies regarding academic integrity. Examples of cheating include (but are not
limited to): Sharing results or other information during an examination. Working on an
exam before or after the ocial time allowed. Submitting homework that is not your own
work. Reading another student's homework solution before it is due. Allowing someone else
to read your homework solution before the assignment is due. 

For more details see the Official UCSC Guideline on Academic Integrity.

Any student who is in need of accommodation, based on the impact of a disability, should contact me privately to submit their Accommodation Authorization and discuss specific needs, preferably within the first two weeks of the quarter. Please contact the Disability Resource Center at 831-459-2089 in room 125 Hahn Student Services or by e-mail at to coordinate those accommodations.
