05/24/05: As usual, the computer has printed a final exam summary sheet
for each student. If you would like to have yours, you may come to Room
2108 Physics and ask Mrs. Robinette for it. (I recommend that you call
ahead (301-405-6115) to avoid the disappointment that no one happens to
be in the office when you come.) Alternatively, send us an envelope with
your address on it and we'll mail it to you. And yet a third possibility:
email me the message (<griffin@physics.umd.edu>)that that you would
like me to put it in an envelope for you in the slot outside my office
(Physics 2109), and you can pick it up there at your own convenience.

05/23/05: Individual Course Records, including letter grade and rank
in class have been posted on WebCT. Use your password to see your own
record. The record includes the Letter Grade = UMEG grade; your rank in
class (of 40); your Course Score, which determines the class rank and
the letter grade. It also includes your Final Exam Raw Score (out of 120),
your Normalized Final Exam Score, your Adjusted Test Score (obtained by
dropping your worst normalized one exam hour score) and your normalized
test score, NTS. In addition, it includes your total Lab score, your Adjusted
Lab Score, yielding the maximum of 100 for all who acquired 80% (160)
of the maximum possible total lab score (200), and your normalized lab
score, NLS. Finally, it includes your Total HW score (out of a maximum
of 132), your Adjusted HW score (with the max of 100 for all who acquired
80% (105.6) or more of the maximum), and your normalized HW score, NHS.
Your Course Score is computed as follows: CsSc = 0.6*NTS+0.3*NLS+0.1*NHS,
and CsSc determines your rank in class and your letter grade. Check Grading
Policy for more discussion of this process. The class' Raw Exam Score
and Course Score histograms will be posted here soon, as well as the Final
Exam text and answer key. |

05/20/05: Final Exam is Friday, 5/20/05, from 8AM to
10 AM in our usual lecture hall, Physics 1410. Click to view
Assigned Seating, which
is the same as that for Exam III. Come on time, but late is better
than not at all. Note that a matching question table covering the whole
course will be posed in questions 99-108. Since these questions may go
more quickly than others, you may wish to treat them out of order. Otherwise
the exam follows the familiar multiple choice format, and the rules are
the same: Open book, any notes and self powered calculators allowed, and
no outside communications devices in the room.We hope to have grades and
course records posted on WebCT by Tuesday. |
|
05/05/05: Ch 14 and Ch 23 (7 lectures in all, out of a total of 39) were
not covered in any of Exams I, II, or III, and will therefore occur in
the final exam with double weight. As a result they will comprise about
30% (=[2*7]/[32+2*7]) of the final exam and the material covered in Exams
I, II, and III will comprise the remaining 70% (=[1*32/46]). |

will be available tomorrow. Check here for an update. ********** |
| 04/29/05(d): Errors found in the Key
to ExIII of F04, posted on 4/06/05, have been corrected by replacing
the key. In #20 a wrong answer was given in which the historically original
fixed points of the Fahrenheit scale (body temperature, 100 deg.F and
temperature of freezing salt brine 0 deg.F) were confused with the modern
fixed points of the Fahrenheit scale (ice and freezing water, 32 deg F =
0 deg C, and steam and boling water (212 deg F = 100 deg C). In problem
#56 a numerically incorrect answer (70 deg C) was given as correct when
the actual answer is 45 deg. C. ********** |

04/29/05(b): Course Re-scheduling to end of semester: We shall omit Ch.15
entirely, and move on to Ch. 23 on Mon 4/2 or Wed. 4/4 in order to discuss
<The Story of the Quantum> and <The Early Atom> in the four
lectures until the last class on 4/11/05. Also HW #12, previously due
on Fri 4/6/05, will not be collected, although we recommend that you do
not omit considering the Ch 23 problems therein. HW#13, about Ch 23, which
was always scheduled for self-grading remains so, but note that Ch 23
will occur in the Final Exam, as will Ch 14, with double weight, so that
this HW should not be overlooked. |

02/14/05: A Practise/Trial Exam for Ch 1,2,3 was handed out today in
lecture. If you missed it, pick one up on Wednesday. The exam is double-stapled

chapters and ready immediately to devote a timed, uninterrupted 25minutes
to doing the exam. Advance peeking, or interruption and return during
the execution, might give you an false edge and make it seeem easier than
it is. The answer sheet is included so that you can self-grade your effort. |
