TUTORS AND MATH CENTER: Free mathematics tutoring is available at the Math Center located in 220 Boucke
Building. For more information, go to the Math Center webpage. If you need extra help, a (paid) tutors list maintained
by the Mathematics Department Undergraduate Office is available on-line at
http://www.math.psu.edu/ug/PrivateTutorList.htm.
EXAMINATIONS: Two 75-minute evening examinations will be given during the semester and a comprehensive
final examination will be given during the final examination period. NO books, notes, or calculators may be used on
the examinations. You must bring your University ID card to all exams. The examinations will be given from 6:30 to
7:45 PM on the following dates:
Midterm Examination I
Wednesday, February 18
Midterm Examination II Wednesday, April 1
Rooms for the examinations will be announced by your instructor at a later date and may also be found on the bulletin
board outside 104 McAllister.
CONFLICT EXAMINATIONS: For the two mid-semester examinations, there is a conflict examination from 5:05
to 6:20 PM on the same night as the regular examination.
Who may take the Conflict Exam? If you have a valid conflict with the regular examination time, such as a class or
other scheduled activity, you may sign up for the conflict exam.
How and when to sign up for the Conflict Exam. Students must sign up for the Conflict Exam in class, with your
instructor, on a pink form. The student is responsible for knowing the room and time of the conflict
examination. This information is on top of the pink form. Your instructor must turn in the pink form 2 class
days prior to the examination date. If you have not signed up with your instructor, you will not be allowed to
take the conflict exam.
Instructions on Conflict Exam night. The student is responsible for knowing the room and time of the conflict
examination. Students must bring their University ID to the conflict examination. The ID will be
checked by the proctor. Although the conflict examination will end at 6:20 PM, no student will be
permitted to leave the examination room before 6:25 PM. Any student who leaves before 6:25 PM will
receive a grade of zero on the examination and will not be allowed to retake it.
MAKEUP EXAMINATIONS: A makeup exam will be given about a week following the regularly scheduled exam.
Who may take the makeup exam? Students who have a valid documented reason, such as a class conflict or illness,
during both the conflict and regular examination times are permitted to schedule a makeup examination with
no penalty. You must be prepared to verify the reason for taking the makeup. Students who do not have a
valid reason for missing the examination, such as forgetting the date, time, or room of an examination, are
permitted to schedule the makeup, but 20 points will be deducted from their score. Students who have taken
either the regularly scheduled examination or conflict examination are not permitted to take the makeup
examination. Students who have not signed up for the makeup with their instructor will not be allowed to take
the exam. The makeup examinations are given from 6:30 to 7:45 PM on the evenings listed below:
Makeup Examination I Tuesday, February 24
Makeup Examination II Tuesday, April 7
How and when to sign up for the Makeup Exam. Students must sign up for the Makeup Exam in class, with your
instructor, on a yellow form, as soon as possible following the regular exam date. The student is
responsible for knowing the room and time of the makeup examination. This information is on top of the
yellow form. Your instructor must turn in the yellow form 2 class days prior to the examination date. If you
have not signed up with your instructor, you will not be allowed to take the makeup exam.
Instructions on Makeup Exam night. Students are responsible for knowing the room and time. On the day of the
exam the room will be posted on the door of 104 McAllister. Students must bring their University ID to
the makeup examination. The ID will be checked by the proctor.
What if a student misses both the regularly scheduled exam and the makeup exam? If a student misses both the
regularly scheduled examination and the scheduled makeup due to a valid, verifiable reason, it may be
possible to take a makeup examination by appointment. All such makeup examinations must be scheduled
through the instructor with the approval of the course coordinator and must be completed no later than one
week after the scheduled makeup examination.
FINAL EXAMINATION: The final examination will be given during the week, May 4-8, 2009. The final
examination may be scheduled on any day during the final examination period. Do not plan to leave
University
Park until after Friday, May 8, 2009. Students may access their final exam schedule Monday, February 16, through
their e-lion account. Notification of conflicts is given on the student's final exam schedule. There are two types of
conflict examinations, direct and overload. Direct conflicts are two examinations scheduled at the same time. Overload
examinations are three or more examinations scheduled within a fifteen hour period, from the beginning of the first
examination to the beginning of the third examination. Students may elect to take the three or more examinations on
the same day if they wish or request a conflict final examination. A student must take action to request a conflict
exam through e-lion between February 16 and March 8. Conflict final examinations cannot be scheduled
through mathematics department, and there will be no sign up sheet in 104 McAllister for the final conflict
examination. Students who miss both the regular and conflict final examinations due to a valid and documented
reason, such as illness, may be allowed to take a makeup final examination. If the student does not have a valid reason,
at least a 30-point penalty will be imposed. All such makeup examinations must be arranged through the instructor
with the approval of the course coordinator, and students in such a situation should contact their instructor within 24
hours of the scheduled final examination. Students who have taken the original final examination are not permitted to
take a makeup examination.
LATE-DROP: Students may add/drop a course without academic penalty within the first ten calendar days of the
semester. A student may late drop a course within the first twelve weeks of the semester but accrues late drop credits
equal to the number of credits in the dropped course. A baccalaureate student is limited to 16 late drop credits. The late
drop deadline for Spring 2009 is April 10, 2009.LATE-DROP: Students may add/drop a course without academic
penalty within the first ten calendar days of the semester. A student may late drop a course within the first twelve
weeks of the semester but accrues late drop credits equal to the number of credits in the dropped course. A
baccalaureate student is limited to 16 late drop credits. The late drop deadline for Fall 2008 is November 14, 2008.
GRADES: Your course grade will be determined by your exam scores and a homework/quiz score (labeled “QZ” by
Testing Services).
Total possible points follow:
Examination I
Examination II
Homework and/or quizzes
Final Examination
Total
100

The exact point requirements for each letter grade will be decided at the end of the course.
A typical distribution follows:
Grade

Points
A, A-
90-100
405-450
B+, B, B-
80-89
360-404
C+, C

270-314
F
0-59
0-269
After the second exam and before the late-drop deadline the guaranteed grade-line cutoffs for the major grades (A, B,
C, D, F) will be provided to facilitate your planning for the rest of the semester. The +/- grade-lines will be assigned
after the final exam. The unavoidable consequence is that some students are just “a point” away from the higher
grade. For the reason of fairness, the policy in this course is to NOT adjust individual grades in such circumstances.
NOTE: Your grade will be based EXCLUSIVELY on the midterm examinations, homework and/or quizzes and final
examination. There is no "extra-credit" work.
DEFERRED GRADES: Students who are unable to complete the course because of illness or emergency may be
granted a deferred grade which will allow the student to complete the course within the first six weeks of the following
semester. Note that deferred grades are limited to those students who can verify and document a valid reason for not
being able to take the final examination. For more information see, DF grade.
ACADEMIC INTEGRITY: Academic integrity is the pursuit of scholarly activity in an open, honest and responsible
manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University,
and all members of the University community are expected to act in accordance with this principle. Consistent with
this expectation, the University's Code of Conduct states that all students should act with personal integrity, respect
other students' dignity, rights and property, and help create and maintain an environment in which all can succeed
through the fruits of their efforts.
Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or
deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and
compromise the worth of work completed by others.
Academic dishonesty includes, but is no limited to, cheating, plagiarizing, […], facilitating acts of
academic dishonesty by others, having unauthorized possession of examinations, submitting work of
another person or work previously used without informing the instructor, or tampering with
academic work of other students. […] A student charged with academic dishonesty will be given
oral or written notice of the charge by the instructor. If students believe that they have been falsely
accused, they should seek redress through informal discussions with the instructor, the department
head, dean or campus executive officer. If the instructor believes that the infraction is sufficiently
serious to warrant the referral of the case to Judicial Affairs, or if the instructor will award a final
grade of F in the course because of the infraction, the student and instructor will be afforded formal
due process procedures.
From Policies and Rules, Student Guide to the University Policy 49-20.
Based on the University's Faculty Senate Policy 49-20, a range of academic sanctions may be taken against a student
who engages in academic dishonesty. Please see the Eberly College of Science Academic Integrity homepage for
additional information and procedures.
QUESTIONS, PROBLEMS, OR COMMENTS: If you have questions or concerns about the course, please consult
