Chemistry 110 Grades and Scores - Fall 2006
Scores are listed by the last four digits of your student number. Please
check all scores for accuracy. Please disregard the plusses (+) and minuses (-)
as only the Letter Grade portion is submitted to the college.
Hope to see all
of you either in an upcoming class or around campus. Happy Holidays!
I weighted the
scores as indicated in the first block of grading. Please note some explanation.
- The fourth exam (E4DR) was originally worth 50 points, but it was
adjusted up to 100 points (E4DR2X) for grade calculations.
- The first three exams (E1, E2 and E3) are from Frigo. The other exams are from Dr. Robertson.
- The three lowest exams have been dropped.
- The average on the Final Exam average was about 72.6%, which I have
adjusted up to about 78%, which is typical for previous semesters. It
is the adjusted Final Exam scores which were used to calculate the Total
Scores value for Letter Grade determination.
- The Flame lab report is out of 30 points, and is included in the lab
scores section.

1Average exam scores are usually between 75-80%.
Your grade for the entire class is based on all scores, not just exam
scores. The average grade for this course will be about a "B" or "B-"
overall. To see where you stand in the class, and a good estimate of
your overall course grade, see where you stand relative to the average exam
score for each exam. If you had a 75% or higher score, and the class
average was 75%, you will be in the "B" or "A" bracket. If your score
was below 75%, you will likely be in the "C" bracket. Your lowest exam
score will be dropped. The course grade percentages given in the syllabus
are for the entire course, not just your exam scores. Everyone does
better in the lab, so your overall percentage for the course will always
be higher than your exam scores. If you are concerned about your exam
performance, please come in and see me during my office hours. Students
who come in during my office hours usually increase their scores about one
letter grade, compared to the scores they would have received by working
through the problems.
As a general rule, exam scores greater than
85% means you will likely be in the "A" bracket and exam scores greater than
70% mean you will likely be in the "B" bracket, based on past semesters.
Your course grade is based on your overall course percentage, which
includes your lab grades, and which usually raises your overall course
percentage.
Final Grade: Your course grade will be based
on the weighting described above. Letter grades are assigned according
to the percentages shown here. |
A |
90% |
B |
80% |
C |
70% |
D |
60% |
F |
<60% |
|
If your Total Score at the end of the semester is within one percent
(1%) of the cutoff (you have 89% and 90% is required for an "A" grade), I
will use your Final Exam percentage to determine your grade. For example,
if your Final Exam score is 90% or higher, you will get an "A" grade. If
your Final Exam is below 90%, you will receive a "B" grade. (Similar
comparisons will be made for "B" or "C" grades, near 80% or 70%,
respectively.) |
Please be aware that all papers have not been recorded. Stay posted
for additional updates.
Grades are listed according to last four digits of your student number. I
believe all scores are accurately recorded. If there is an error, please
let me know immediately (email or in person).
The raw score for the Final Exam is shown in column F1. Not knowing
what should be the average for the multiple choice exam, I adjusted the highest
raw score (80 points out of 100 total) to 100 points (multiplying by 1.25).
Every score was adjusted by this same multiple, yielding a class average
score of about 78% (compared to the raw average of 61.7%). This adjusted
average is close to the average for the other exams taken during the semester,
which is likely to have been the average, if an exam using the regular format
had been given. I feel comfortable with this adjustment, and believe
that the overall ranking of the class is consistent, based on this adjustment.
Therefore, to see your Final Exam score, which is counted, look in
the Final Adjust column. The Final Exam score used in determining the
course grade has been adjusted to 200 points, and is shown in the Final Subtotal
column.
The Letter Grades shown here will likely be the grades turned in on Friday.
Disregard the plusses (+) and minuses (-), as they will not be included
in the final course grade that is turned in.
Thank you for taking in this organic chemistry class. I have enjoyed
interacting with each of you. I look forward to seeing most of you
next semester. Happy Holidays!
To gage
your final grade for the course, examine the following. Grade cutoffs
are:
A: 900 points; B: 800 points; C: 700 points; D: 600 points
Look at your Total Score. Since the Final Exam is worth 200 points, add
these 200 points to your Total Score to see the maximum grade you could receive.
For example, if you have 649 points, the maximum points possible would be
849 points, putting you into the "B" bracket. Also, to see the score
you would need to just barely make the "B" bracket, subtract your Total Score
(649 points) from the "B" bracket cutoff (800 points). You would need
151 points on the final exam, which would be a 75.5% score.

Grade for the class. Please disregard the Letter Grade information,
