Random end of classes updates

Ok, it is the end of days ... for ph102 anyway. Several things:

1) There is no lab on Wednesday. You can have the afternoon off to study ... or whatever it is you do. I suggest studying ;-)

2) The final quiz and lab grades are now up on Moodle, as is Exam II. Homework 3 will appear sometime Tuesday evening. After that, all is left is homework 4 and the final. Recall the grade weighting from the syllabus.

3) Homework 4 can be handed in with the final exam without a late penalty.

4) Somewhere in the depths of a heinous sleep-deprivation-induced lapse in judgment, I decided that the final exam will NOT cover waves, quantum or atomic physics (i.e., this week's material).

5) The final *will* cover Relativity, Electricity, Magnetism, Induction, Circuits (ac & dc), and Optics (i.e., everything except this week's material). Study your homework, old homework, and old exams. Oh, and the book and notes.

6) The final will be, contrary to previous rumors, more like 75% multiple choice and 25% problems. It will be held at 8am, this Friday, in our normal classroom.

7) The exam II average was 89%, with a standard deviation of 8.5%. Below is the distribution for exam 2, plotted as the percentage of people choosing each question, and of those, the average score. Clearly, each question should have had a 50% chance of being chosen if they were all equal. Apparently, they were not ... certain questions were perceived as being much harder than others ...

8) There may be a review session on Thursday. Stay tuned.

9), 10) Intentionally left blank.

11) This one goes to eleven.
