Office Hours:

NOTE: Office hours listed below are suspended on the day before major exams and finals, giving me time to make them out.  Do not wait until the day before a major exam for help, unless the tutor has office hours and can help you on that day.

Half of my time is spent teaching CVEN 305. During the remaining hours I serve as a departmental adviser for about 100 C.E. students and another 100 CHEM students.  Since I have limited time for tutoring please plan on assistance either during my office hours, or visit the help desk.  Don't wait until just before class or a quiz to get help or you likely won't get any, especially around quiz days.

It will always be in your best interest to call to make sure I have not been unexpectedly called out before you come by, unless you are already in the area.

Help Desk:  Tutoring hours for help in the class can be found here

To find them go down the stairs to the basement, turn right, and it's the first door on the right.  Room 030 CE Building.

Grader: Sagar Dalal - Email questions regarding homework grades only  

Textbook: The textbook is excellent - one of the best:

Looking for a used textbook? Starting Fall 2104: ISBN number:  9780073398235

Note that the internet is a thieves paradise. If they won't show you this cover, it's probably not the correct 7th edition.  Also, although the international editions are inexpensive they may be all metric including both the example problems and homework problems.
