HOMEWORK Homework assignments will be given during the lecture periods. The assignments are due at the beginning of class on the due date.

EXAMS All exams will be closed‐book, closed‐notes exams. You are not permitted to store formulas, problems solutions, etc. on a programmable calculator. If you are caught violating this rule, there will be a minimum penalty of receiving an “E” in the course. No cell phone use is permitted during exams.

GRADING Grading is based on three midterm exams, a final comprehensive exam, and homework. The tentative exam schedule and weights are listed below.

Exam 1 Wednesday, September 23 22% Exam 2 Wednesday, October 21 22% Exam 3 Wednesday, November 18 22% Final Exam Monday, Dec. 14 at 12:00 p.m. 24% Homework 10%

Grades: A = 90 ‐ 100% B = 80 ‐ 89.9% C = 70 ‐ 79.9% D = 60 ‐ 69.9% E = below 60%

Office Hours: MTWRF: 2:00 ‐ 2:50 p.m.

Because my posted office hours may conflict with your schedule, or otherwise be inconvenient, I have provided my class schedule to help you make arrangements for meeting at times other than office hours. Generally, I will be available anytime except one hour before each class. However, it is best to call or e‐mail me to make sure I’ll be in my office.

Text website: http://www.mhhe.com/engcs/electrical/cathey/ The text website has a link to an errata document that lists errors in the textbook. Most of the errors are typographical; however, it is very important that you correct the errors in your textbook. The text website also has a link to additional problems (and solutions) that you may find helpful.

Course website: http://www.engr.uky.edu/~jsottile/ (Can also go to the ECE homepage to >Faculty and Staff>Joseph Sottile>Personal Page (Click on link to EE 415G.) The course website is for your convenience. It will have links to homework assignments and due dates, tentative exam dates, and any other information relevant to the course. Although I try to maintain the website regularly, there may be times in which the assignments will not be posted immediately. Therefore, it is very important to come to class to receive homework assignments and other information. 5.2.4.6 Dead Week [US: 4/10/06; 4/13/09]

A. The last week of instruction of a regular semester is termed "Dead Week." In the rest of these Rules, this term also refers to the last three days of instruction of a summer session and a summer term. B. In cases of "Take Home" final examinations, students shall not be required to return the completed examination before the regularly scheduled examination period for that course. C. No written examinations, including final examinations, may be scheduled during the Dead Week. D. No quizzes may be given during Dead Week. E. No project/lab practicals/paper/presentation deadlines or oral/listening examinations may be scheduled to fall during the Dead Week unless it was scheduled in the syllabus AND the course has no final examination (or assignment that acts as a final examination) scheduled during finals week. A course with a lab component may schedule the lab practical of the course during Dead Week if the lab portion does not also require a Final Examination during finals week. F. Make‐up exams and quizzes are allowed during Dead Week; these are exempt from the restrictions stated in C, D, and E. G. Class participation and attendance grades are permitted during Dead Week.
