Grading Criteria

Your semester grade (90-100 A, 80-89 B, 70-79 C, 60-69 D, Below 60 F) will be determined as follows:

4th Six weeks

26 2/3

5th six weeks

26 2/3

6th six weeks 26 2/3
Semester Exam 20

The grade for each six-weeks is calculated from three categories:

  A.  daily average  (homework, daily quizzes, class work, etc.; one grade for every 10 is dropped unless it is a marked zero.)

  B.  exam average  (usually 3 or 4 exams per six weeks, the notebook grade is sometimes included here as half an exam grade)

  C.  six weeks exam

This results in homework, daily work, quizzes 20%; major unit exams 60%; final exam 20%  


All grades will be posted on AC Online. Be aware that the Family Educational Rights and Privacy Act of 1974, as amended, prohibits instructors from disclosing information regarding grades over the phone, via email, or to a third party. Thus, if you need to discuss your grade with me, you must do so in person or check online.


Regular attendance is necessary for satisfactory achievement. If an absence occurs, the student is responsible for the information and assignments covered in class. Each student is expected to cultivate at least one other student in the class as a contact person who will be in attendance during an absence.  The contact person should take notes, pick up needed handouts, assignments, etc. The absent student should make arrangements with the contact person so that he/she can receive what is needed to expedite making up for the absence ASAP and will be better prepared to be able to participate in classroom learning on his/her return.

Please remember the deadline for dropping a class at AC.(April 21, 2022) If you stop attending class and your average drops below a 60 due to missed assignments and you do not drop the course by this deadline, you will receive an F for the course.

Additional Information

There is generally a homework assignment daily.  Most homework assignments are graded and assigned a numerical grade.

In my paper grade book, daily work is sometimes marked with a code.

  I         to indicate the was incomplete (not finished)

  W       to indicate something was wrong in the way the work was done

  H       the heading was missing, illegible or incorrect

  Q       indicates a zero that does not drop; usually for an assignment not done but also for cheating.

A marked out grade followed by a circled grade indicates the student took advantage of an option sometimes given to replace a low daily grade with a quiz after the student has redone the assignment.  The quiz grade (minus 20 points for a homework or minus 10 points for a quiz) replaces the daily grade.
