Textbook use is supplementary to the lectures.

Online homework is used for general chemistry courses (but not for biochemistry).

A non-programmable calculator is required.


General chemistry lectures: homework/quizzes 20%, exams 60% and a comprehensive final 20%.

General chemistry labs: lab reports 50%, quizzes 20-30%, exams 20-30%.

Biochemistry: quizzes 10%, exams 70%, comprehensive final 20%

Homework Policy

The online homework will have specified due dates to receive credit for the assignments.
