Course Requirements

An independently written report of each laboratory assignment is required.

Unless previously arranged with the Instructor, no credit will be given for late assignments. All assignments are due at the announced due date and time.

All assignments must be handed in to Dr. Whitcomb or Dr. Reed in class or at their offices in CSEB. Do not hand in anything to the TAs. The TAs are not authorized to receive assignments. The lowest score laboratory will be dropped.

Course grade will be determined by lecture and laboratory participation, written laboratory reports, a class project, a midterm exam, and a final exam. The relative percentages will be something like the following (this is subject to revision): written laboratory reports (40%), class project (20%), quizzes throughout the quarter (15%), and a final exam (25%).


  • Physics I and II
  • Calculus I - III
  • Linear Algebra
  • Differential Equations

Exam Schedule

Exams are cumulative, closed book, closed notes, closed cell-phone, calculators are OK.

  • Midterm Quiz: Friday, March 13, 2009 at 1:30pm (in class). Several other unannounced quizzes will be given in class.


Grades are posted here.
