The Extended Ed sections are not listed in the regular class schedule (there is a separate class schedule for the College of Extended Learning), but they are available through touch-tone. NOTE: After the touch-tone deadline has expired, please register for the Extended-Learning lab section at the Physics and Astronomy Department office, TH 334. You will need to leave a check for $175 there with your application. The section will only be taught if there are enough registrations to pay its way. If the section does not go, your check will be returned uncashed.
