FINAL EXAM	Tuesday 12/17/19 4:10-7 & 7:30-10:20pm	Exam #4. EMPHASIZES LECTURES 20-23, but will refer back to entire course. Important: UN2005, section 1 students: This is not the usual time for a class that meets Tu-Th at 10:10. Please take this into account when buying tickets to go home.	Rooms TBA
** 110 minutes (4:10 to 6:00) will be scheduled for exams, given availability of rooms. Students with class or work conflicts at 4:10 may take the exam later -- time TBA (requires permission, including proof of class conflict: CU SSOL printout of schedule with your name or a note from employer). Students with class or work conflicts at both times must contact the course assistant in 600 Fairchild, 854-5388) at least one week in advance.
++Download codes: LH, lecture texts in html, best for viewing on a screen LP, lecture texts or PP in pdf, best for printing (PDF = notes in PDF for lectures 11-end) M, audio of lecture in mp3 format W, audio of lecture in WMA format PP, PowerPoint, if used in lecture Out, outlines for lectures 11-end. (In Word)
Web lectures and outlines are usually provided before the morning lecture if not the night before. All of the 2018 lectures are available for those who want to look ahead. (See link at top of page.) There are links to figures in the 9th ed. of Savada embedded in the lectures. Answered questions posed by students in previous years are also provided: follow the red Q&A links to see a more complete explanation; the green Q&A links expand upon a subject.
Savada and Purves refer to the same basic text: Sadava is the first author from the 8th edition on, Purves was the first author of editions 1-7.
Note: Regarding exams, students are responsible for the material presented in lectures, the Web lectures text, the handouts, and the problems. The texts should be used only to help understand the lectures; you are not responsible for any topics or information that is in the text but not in the live and Web lectures, handouts, or problems. Additional material is sometimes provided in the Web lectures in the form of links to outside sources and links to additional pictures and diagrams; you are only responsible for the information seen on the Web Lectures and the handouts.
