Class Web Sites and Student Privacy
Web-based, password-protected class sites will be associated with all academic courses taught at The University. Syllabi, handouts, assignments and other resources are types of information that may be available within these sites. Site activities could include exchanging e-mail, engaging in class discussions and chats, and exchanging files. In addition, electronic class rosters will be a component of the sites. Students who do not want their names included in these electronic class rosters must restrict their directory information in the Office of the Registrar, Main Building, Room 1. For information on restricting directory information see:
http://www.utexas.edu/student/registrar/catalogs/gi00-01/app/appc09.html

Add-Drop Period
After the end of the add-drop period you may drop in compliance with the rules for the School of Engineering: An engineering student must have the deans approval to add or drop a course after the fourth class day of the semester or, after the second class day of a summer term. Adds and drops are not approved after the fourth class day except for good cause. Good cause is interpreted to be documented evidence of an extenuating nonacademic circumstance (such as health or personal problems) that did not exist on or before the fourth class day. Applications for approval to drop a course after the fourth class day should be made in the Office of Student Affairs, Ernest Cockrell, Jr. Hall 2.200.
12
Course/Instructor Evaluation
Course / Instructor evaluation will be conducted on 11/30/2009 using the Common University Form.
13
Final Exam
A Take Home Final Examination will be conducted at the end of the semester.
The exam will be handed out on Monday, November 30 during class and due no later than 5:00 PM on December 11.
The examination will be cumulative and will allow the use of the course text, notes, and handouts.
Individual effort is required for the exam.
