Final is on Tuesday, Dec. 20 at 2pm in Merrill 204. You can bring 3 sheets of notes, calculator, and writing implement. I will provide the exam and the blue book. Good luck!
PSD Sample Problems
Exam 3 grades posted
Exam 3 grades are posted in the gradebook. Score is listed in points out of 150. Your exam will be passed back on Monday after break during class.
Exam 3 essay questions
The essay questions for exam 3 are listed below. You may bring a solution with you to the exam on Wed. night. If you forget you will be able to answer the essays during the exam.
No Class tomorrow 10/31/11
Happy Halloween! No class tomorrow. I had to head for the hills (aka Cambridge) after a branch punctured the roof of my house and the power went out. No homework this week, please read Ch. 13 on Hamiltonians.
Canceling Problem Session on Tuesday
Due to low attendance I am canceling the problem session on Tuesdays. Most of you just stop by my office in the afternoon. If there is a better time that works let me know and I will reinstate it. :) In any event there is a faculty meeting tomorrow so I won't be able to meet with anyone in the evening.
Exams are Graded
I have graded the exam and passed back both the exam and the solutions. Please look over your grade in the gradebook, as I recorded these at 2 am and so there may be mistakes. The exam is out of 135 points, but your grade in the gradebook has been renormalized to 150 points (i.e. take your score divide by 135 to get the percentage and then multiply by 150 to get the grade in the gradebook). For those that have emailed me or talked to me after class I have already updated your score. Please let me know of any changes as soon as possible.
I have included the histogram of student scores. The mean is a 71% with a width of 8%, and 9 out of 15 students scored above a 70%.
I am very happy with the results of this exam. You did very well! I am also happy with the length of the exam given the amount of topics we covered in the class. I am only not happy about one aspect - that there were many small mistakes that could have been avoided with more careful inspection. So in the future the format of the exam will be the same, but I will give you an extra hour to work on the problems. Please note that the next midterm will be 3 hours long; the final will remain unchanged at 3 hours long.
Class Announcements 10/5/2011
I made a whole slew of announcements today in class. To make sure you got them all, I have summarized them below.
1) Homework on Ch. 6 will now be due on Oct. 19 (Wed. at midnight). This should allow you more time to study for the exam.
2) Exam on Oct. 12 (Wed. 7-9pm) in Merrill 211. The exam will be 2 hours long and will be the same format as the intro mechanics exam. There will be 5 math problems, 5 multiple choice problems, and 3 essays questions of which only your best essay will be graded. The 3 essay questions will be given out before the exam and you may complete them at home and bring them in with you to the exam. You will also be allowed to use one 8.5X11 inch sheet of notes during the exam. I will not provide equations.
3) Please email me with any questions about the material from Ch. 1-5 by Friday. I will address these questions during Friday's lecture. After reviewing these questions I will start to discuss Ch. 6.
I have placed the solutions to the homework problems on reserve at the science library. Do not take the solutions out of the library and do not photocopy or scan the solutions. You will notice that there are solutions to other problems besides the assigned problems. You can take it upon yourself to do these problems in preparation for the exam or as study problems. O
Ultimately, you will want a record of the solutions. You should correct your own homework sets and these should serve as your record. Again my goal is to have everyone do and understand every problem.
