Various Course Announcements, dated, are posted here, latest at the top (including posting dates of HW solutions and links to the solutions themselves):
**********

12/21/05A:Each individual's CourseLetter Grade(LG), Rank in Class (Rank/64), Course Score(CsSc), Adjusted (by dropping the lowest exam hour's renormalized score) Test Score (AdjTS), Normalized Test Score (NTS), Raw Final exam score (RawFnl/120) and Normalized Final Exam Score (NFnl/133.9) has been posted on WebCT. In addition, the (RawLab/220) score, the adjusted (for the "80% is Enough" rule which gives the highest grade of 100 to every student who scores 80%, = 176 of 220, or more, of the maximum possible total lab score) Lab score (AdjLab/100), the Normalized Lab Score (NLS/75.0), the total raw HW score (RHW/144), the adjusted HW score (AdjHW/100), and the Normalized HW score (NHS).

The rank in class was defined by the Course Score: CsSC = 0.6NTS+0.3NLS+0.1NHS, and letter grades were assigned from the top down, with the break points set by gaps adequate to distinguish the highest B from the lowest A, etc. These break points turned out to be A(20)>79.5, B(12)>71.9, C(28)>42.5, F(2)<15.1.
We hope to post histograms of the Final Exam Raw Score Distribution and of the Course Score Distribution here as soon as possible.
**********

12/14/05: you may retrieve your unreturned course materials (Labs, HW's, Exam reports, etc.) from Dr. Griffin and/or
Mrs. Robinette (Room 2108A Physics :301-405-6115). Call ahead to make sure that someone will be here to help you
when you arrive.
*********

12/11/05: A corrected version of the S05ExIII-KEY-Corrected has been posted, since the answers to #58 and #59 were wrong on the previous key. Detailed solutions to these problems have also been posted to clarify the corrections: S05ExIII#58-#59. Finally the (only slightly) modified Histogram of our ExIII scores' distribution has been posted: ExIII-correctedDistribution. (Recall that #14 had TWO correct answers - see below.)
**********

12/9/05C: The corrected Exam III Raw scores for students who answered (B) on the poorly posed Question #14 of Exam III, and the corrected Normalized scores of all students, have been uploaded to WebCT, where one can can use the password to view them. Students who answered (B) on question #14 gained two points in their Raw Scores, now labelled CrRExIII on WebCT, and typically about 2 two points in their renormalized scores, more or less depending upon where their scores lie in the distribution. All other students retained the same Raw Score, and had small shifts in their Normalized Score, now labelled CrNExIII on WebCT , due to the increase in the class average from 62.8 to 63.6 and of the standard deviation from 14.6 to 14.7.

*********

12/6/05B: The S05FinalExam, except for page 10, and S05FinalExam-p10 have been posted separately. Click to view each.Also the S05FinalEx-KEY has been posted.
**********

12/6/05A: The Distribution of Exam III Raw Scores has been posted,and individual student grades have ben upoladed to WebCT, where one can use his password to view his own Raw and Renormalized Exam III scores. (The maximum possible Renormalized Exam III score, corresponding to 60 correct answers out of 60, was in this case 148.6.) Also theDistribution for the Exam II Raw Scores published earlier was erroneous, and the corrected version has been posted today.

12/1/05A: Assigned Seats for Exam III tomorrow have been posted here. Click to view.
**********

11/21/05: Exam III on Fri 12/2 will cover Ch 10, 11, 12 (pp233-244 only ), and Ch13. Chapter 14 will NOT be covered in Exam III, but instead will, (like all the course material not covered in Exams I, II, and III) be given double weight in the final exam (scheduled for Mon 12/19/05 at 1:30 PM in our usual lecture hall, Physics 1410). Also, HW #11, on Ch 14 not to be included in Exam III, will for your convenience not be collected until Mon. 12/5, after Exam III. (But note that HW#12 is still due Wed 12/7.)
**********

11/17/05A: We have posted today one page of notes on how the Ideal (of "Perfect") Gas Law follows from elementary consideration of gas particles travelling freely in straight line paths, except for collisions with the walls of the container, which are assumed to be totally elastic; i.e. the particle has the same kinetic energy after the collision as before. Click
PerfectGas to view.
**********

11/11/05: To keep in linewith the lecture coverage, HW#9 due date is postponed yet again from Mon11/14 to
Wed 11/16, and Hw # 10 from Fri 11/16 to Mon 11/21/05.
**********

11/09/05: Note that, as the Syllabus indicates, Ch 12 coverage will be abbreviated: We will cover only pages 232-242, omitting <Sink or Float>, and <Bernoulli's Eeffect>.
**********

11/1/05a: Individual ExamII Raw and normalized scores have been posted on WebCT. Go to <www.courses.umd.edu/index.htm> and use your password to see your grades. (120 = 2* 60 was the maximum possible Raw score for Exam II, and that would yield the maximum possible normalized score of N= 128.0.)
**********

10/27/05: The click to view label for HW#9 solutions is HW#9Solutions. (This line omitted until 11/2/05.)
**********

10/26/05A: Exam II on Friday (Ch5,6,7, and 9 (and pages143-144 ONLY of Ch8)); Pre Exam II Q/A session tomorrow, Thursday 10/27/05, at 6:00 PM in our lecture room, Physics 1410.

**********

10/07/05A: Yesterday's upload of ExI etc. scores, discussed below, was unsuccesful. The upload has been repeated.
You can use your password to see your grades at the WebCT address given below under Physics 117 Fall 2005,
(not Winter 2006).
**********

10/04/05B: Exam I has been regraded from scratch. New student exam reports will be available on Wednesday. The regrading corrects for the fact that no problem #16 existed in the printed exam, and for the fact the our answer key
had erroneous answers for problems #8 (e, or 4, is correct) and #39 (c, or 2, is correct). The new exam reports will reflect these corrections. Click to view the corrected ExIGradeDistribution histogram.
