Course Requirements:
  Three tests
  Final exam (April 30, 11:30 AM - 2:00 PM)
  Written assignment

Grading:
Grades will be assigned according to the scale:

  A     92 - 100
  B     80 - 91+
  C     70 - 79+
  D     60 - 69+
Four tests will be given including an equally weighted final exam. The final exam will include not only the last block of material, but also optional questions that can add points to previous test scores. To help you prepare for these tests, non-credit homework problems similar to test questions will be provided from class. Because no textbook is used in this course and to fulfill the requirements of a writing intensive course, the notes you take in class will be graded. This will require that you rewrite your notes as if you were writing your own textbook. Students who receive a grade of D or F on this work will be referred to the English Proficiency Committee.

Attendance Policy:
You are responsible for all course material, assignments and instructions given in class; neither absence nor inattention waives these responsibilities. Assignments are expected to be submitted on time and tests taken on the day assigned unless prior arrangements have been made. Exceptions may be made in the event of a verifiable emergency. You are expected to attend all lectures and labs. A grade of F will be assigned if you fail to attend three-fourths of the labs or lectures. It is your responsibility to inform me of your presence immediately after class if you arrive after roll is called; else you will be considered absent.

Honor Code:
The Honor Code has four basic provisions which strictly forbid lying, cheating, stealing and plagiarism. These provisions are standards of integrity and are moral obligations that your are expected to keep in this course.

Other items:
A calculator capable of performing trigonometric and logarithmic operations is needed.
