A roll call will not be taken but attendance is required in all lab sessions. Lab sessions are for getting help interactively for your lab assignments. The first fifteen minutes of each lab session are especially important to attend since the instructor will provide directions for successful completion of that week's assignment.

However, please note that most lab assignments will require a few additional hours outside of lab sessions in order to finish your assignment. Also please realize that the instructor's and TA's office hours are not meant to be used as substitutes to lab attendance.
