GRADING POLICY FOR CHEM 103 – Dr. Talaty
There will be a total of 1,000 points during the course, distributed as follows:
Lecture
Hour exams
Homework
Quizzes
Final Exam
375 points
50 points
50 points
225 points
Laboratory
Write-ups
Quizzes
Exams
176 points
44 points
80 points
NOTE: Although the lab grade is only 30% of the total grade, completion of the lab section of
the course is MANDATORY. Any student who does not turn in ALL of the labs will receive a
failing grade.
HOUR EXAMS: There will be three hour exams during the semester. Each will be worth 125
points. None of the scores will be dropped. Scores on these exams will be determined as
follows: the average of the TOP 3 scores in the class will be calculated. This average must be
greater than 85%. This average will be considered the total number of possible points on the
exam. A particular student’s score on the exam will be calculated dividing his/her raw score by
this average and then multiplying by 125. For example, if the average of the top 3 scores on
any exam is 104 out of 125 and you receive a raw score of 83, then your actual score will be
83/104x125=100 out of 125.
FINAL EXAM: The final exam will be worth 225 points. This will be a comprehensive exam,
which means that it will cover the entire course, not just the material after the last exam. Each
student’s score on the exam will be determined in the same manner as for the hour exams,
using 225 instead of 125.
HOMEWORK: Homework will be assigned approximately once a week. Each homework
assignment will be worth 10 points. However, there will be more than 8 homework assignments
during the semester, so only the top 5 scores will be used.
QUIZZES: Quizzes will be given periodically during the final 15 minutes of the class period and
will be worth 10 points. Again, there will be more than 5 quizzes during the semester and only
the top 5 scores will be used. Quizzes will be announced during the preceding lecture.
Once the scores for the various components have been determined as described above, they
will be summed to give a final score. The following scheme will then be used to assign a letter
grade:
A
900+ points
B
800-899 points
C
650-799 points
D
500-649 points
SOME COMMENTS, POLICIES AND SUGGESTIONS
Use all of the resources available, especially your instructor. You should feel free to ask
questions in class, after class, or if you should happen to run into me in my lab (301 MC). If you
need some help, make arrangements to talk to me at some other time.
Remember that chemistry, like all science courses (as well as things like math and languages),
is a subject in which one concept builds upon the previous ones. Therefore if you fall behind,
you will probably become hopelessly lost. So keep up! This means coming to class, looking
over your notes, reading the book, and doing the homework problems. Studying for an exam
ins useful but if you try to cram for an exam without having kept up, you will have a tough time.
Attendance in lecture is not mandatory, but highly recommended. You will be held responsible
for anything that is discussed in lecture, including material that may not be in the book, quizzes
and announcements thereof, changes in scheduling (e.g. of exams), etc.
Policy on missing quizzes, exams, etc.:
Quizzes cannot be made up. There will be enough quizzes offered during the semester that if
you should be absent for a couple of them, you will still have at least five quiz scores to use.
The only acceptable excuse for missing an exam is illness (YOUR OWN!). If you are ill on the
day of the exam you must do BOTH of the following:
1. Call me at my office number BEFORE the exam is scheduled to start. If I do not answer,
leave a message with the Chemistry Dept. office.
2. Get a note from a doctor. This note should be dated for the day of the exam and can be
from your personal physician or from the University Student Health Services.
You will be expected to take a makeup exam AS SOON AS YOU HAVE RECOVERED.
The only acceptable excuse for missing a lab is illness. Labs can be made up during the two
makeup periods (see laboratory schedule). In order to be allowed to make up a lab, you must
follow the same two procedures listed above for missing an exam. At the next lab session, be
sure to arrange with your TA to have the makeup lab ready during the makeup session.
The periodic table will ALWAYS be available for your use.
You are welcome and encouraged to study with your friends. If you do homework assignments
together, each person must turn in his/her own paper to receive credit. Remember also that
you WILL NOT be able to get help from your friends during exams. Therefore it is in YOUR
OWN BEST INTEREST to work on homework assignments on your own before getting help
from others.
Please remember to turn off all cell phones, pagers, etc., before you enter the lecture hall. This
is only fair to me and your fellow classmates.

LABORATORY
Chemistry is best learned in the laboratory setting. With this in mind, we have developed a lab curriculum
to facilitate your understanding of the basic principles of chemistry. Hence, your grade in CHEM 103 is
largely dependent on your laboratory work. Failure to complete any of the labs or tests will result in a
failing grade for the lab and thus, a failing grade for the course.
Two make-up lab days are provided; one for each half of the semester and only one lab may be made up
on each particularly day. If you miss a lab please ensure that you contact your TA about the absence.
We recommend that you work in pairs to do the experiments. Having a lab partner will improve your
understanding of the lab because you’ll bounce ideas off each other and collectively work together. You
will each submit your own laboratory report.
SAFETY
It is expected that you adhere to standard safety procedures in laboratory. This includes proper attire:
eye protection (either goggles or safety glasses), shoes that cover your feet and toes, pants that go down
to your ankles and shirts that protect your torso. Your purchased laboratory package includes gloves and
other equipment. Proper safety techniques and other safety issues will be addressed in lab and should
be stringently followed. FAILURE TO ABIDE BY THE SAFETY GUIDELINES WILL RESULT IN
EXPULSION FROM THE LAB AND WILL COUNT AS A LABORATORY ABSENCE.
GRADING
At the beginning of each laboratory, a 5 minute quiz, worth 2 points, will be given to ensure you
understand the day’s laboratory. Each laboratory report is worth 8 points, and is due a week from the
completion of the laboratory. Since lab # 4 and #11 require two periods to complete, they will be worth 18
points each and only have one quiz. The final and midterm exams are each worth 40 points. The total
lab grade will be normalized to ensure uniform grading.

The Department of Chemistry accepts payment by personal check with
correct address, contact information and reserves the right to withdraw that
privilege at any time. A valid Shocker Card must be presented. If a check
should be returned for insufficient funds, student(s) will be locked out of
their laboratory drawer and will be unable to do the experiments required
for passing the class. Questions regarding this policy may be addressed to
the Department of Chemistry, 206 MC, (316)978-3120.
Policies & Procedures for Lab Grade Transfers
Students repeating CHEM 103, 211, 212, 531 and 532 may
transfer their lab grades if they meet the following criteria:
1. The chemistry course (lecture and lab) students are repeating
was taken at Wichita State University.
2. The chemistry course (lecture and lab) students are repeating
was taken within three (3) years of the repeating semester.
3. Students must complete and sign the REQUEST FOR
TRANSFER OF PREVIOUS LAB GRADE form obtained from the
Chemistry Department office (206 MC).
4. The faculty member from the repeating course as well as the
current course professor must approve (sign) the REQUEST FOR
TRANSFER OF PREVIOUS LAB GRADE form. Faculty
members may not approve this request if they believe lab points
are too low to assist the student during the current semester in
passing or raising their grade.
5. The completed REQUEST FOR TRANSFER OF PREVIOUS
LAB GRADE form must be returned to the Chemistry Department
office (206 MC) on or before the deadline date for each semester:
A) Fall & Spring – the Friday of the second week of classes –
AUGUST 28, 2008.
B) Summer – the Friday of the first week of classes.
Effective Summer Semester 2007, students who receive a grade
of “F” for CHEM 103, 211, 212, 531 or 532 MAY NOT transfer
their lab grade.
Questions concerning this matter may be addressed to the
Department of Chemistry, room 206 MC.
