LSU Phys 2101 Spring 2008 Section 3

Physics 2101, General Physics for Technical Students, Spring 2008

Section 3 (MWF 12:40-1:30pm)

We will post here news that pertain to our section. Please visit the link to Phys 2101, Spring 2008 webpage to see news that pertain to ALL sections.

Final Course Scores : calculated as explained in the syllabus: score = (0.5*X1+X2+X3+X4+2*FX+0.5*HWK)/6; using all exam scores (X1, X2, X3, X4), final exam (FX) and final homework scores (HWK). I have taken into account all special circumstances I know about. I have submitted letter grades to PAWS using the grade scale in the syllabus.
Final Exam: scores, histogram, solutions, formula sheet.
Final Homework Scores (1-14)
Course scores (April 21): I used scores from Hwk 1-11 (including extra credit syllabus), plus scores of the 4 exams taken during the semester. The formula I used for the course score is: ((X1*0.5+X2+X3+X4)*550/350+HWK*0.5)/6, resulting in a number between 0 and 100; I assigned a letter grade following the scalce in the syllabus. I have taken into account all excused absences that I know about. Please let me know if my records differ from yours!
The last four columns, labeled "A", "B", "C", and "D", are the scores you need to get in the final exam (out of 100) to get that respective grade in the course. If the number is larger than 100, it means that unfortunately, your final score will not reach what's needed for that grade (this happens most often in the "A" column). If the number is negative, it means that you can get that score even if you miss the final exam (this happens most often in the "D" column).
Exam 4: scores, histogram, solutions, formula sheet.
Course scores (April 2): I used scores from Hwk 1-9 (including extra credit syllabus), plus scores of the 3 exams taken so far. The formula I used for the course score is: (X1*0.5+X2+X3)*550/250+HWK*0.5; I assigned a letter grade following the scalce in the syllabus. I added the midterm score submitted in March for reference. I have taken into account all excused absences that I know about.
Exam 3: scores, histogram, solutions, formula sheet. We will add 10 points to the score of this exam.
Midterm grades and histogram, calculated using Hwk 1-5 scores, plus the first two exams. I have used the grade scale in the syllabus for the course score I calculated. I have assigned 183 points to Exam 1; 367 points to Exam 2 (so both exams together count for 550 points); and 50 points to the homework score, for a total of 600 points. I have taken into account all special cases I know about (excused absences, late additions, etc), so please let me know ASAP if my records disagree with yours.
Homework 1-5 scores, plus the syllabus extra credit. The "total" score is calculated weighing all six assignments equally, and dividing by 0.45 (90% of the available 500 points from the Hwk assignments). Notice that even if you keep doing as well in the future as in the first five assignments, your score may go down somewhat, because the maximum possible score, including the extra credit, will not be as high (but it will still be higher than 100).
Exam 2 scores, our section's histogram. We will add 5 point to the score shown.
Exam 1 scores, our section's histogram, all sections' histogram. If you got less than 60%, please make sure you identify your weak points, and work on them; you will need to know all the material tested to be able to learn the material in the rest of the course.
Exam and homework solutions are here.
Extra credit opportunity: if you read the syllabus (course webpage), and bring a signed copy of the first page of the syllabus to your instructor before Friday Jan 25, we will add to your homework score an extra assignment with a perfect score.

The lectures posted (PowerPoint files) are preliminary, you are very encouraged to read them in advance, and have your questions ready to ask in class.
Some of the slides with examples have their solution worked out in the "notes" you can read in PowerPoint.
