Online Homework: Please bookmark the online homework webpage You can access your weekly homework there.

Your login is your SPIRE user name, that is the first part of your email address: If your email is, your login is dfgg. Your password is currently set to be your student ID. When you login for the first time you should change your password.

It is a good idea to print out a copy your homework and add it to your notes.

Grading: There one midterm exam worth 1/3 of the grade and one final exam worth 1/3 of the grade. Homework are assigned weekly and done on-line on the Webwork system.

  Scales for letter grades:     A : 90     A-: 87     B+: 83     B : 79     B-: 75     C+: 71     C : 67     C-: 63    D+: 59    D : 55     F : < 55

Exam schedule: There will one midterm exam and one final exam. The material covered in the first midterm will be announced in due time. The final exam is comprehensive but will cover mostly the material of the second half of the semester.

Weekly Schedule

The following is meant to give a general idea of which sections are covered in which weeks and may be adjusted as needed. All the sections will be covered.
As a general principle the material in a given week will be subject of the homework due the week after to leave you time to review the material.
