Attendance Policy, Professor Jussim, Social Psychology, 830:321
Sections 03 and 04, Spring, 2009

I do not take attendance.  In that sense, it is not required.

However, please consider this before skipping many classes.
Let's say you are very smart, and can answer 90% of the
questions from the book correctly.  About 70% of the questions
are from the book.  This, so far, gives you a grade of about 63%. 
And let's further say that you skip most classes.  Therefore, you cannot
possibly answer most of the lecture questions correctly,
except for guessing.  So, let's say you get 30% of the lecture
questions correct.  30% of 30%=9%.  So, your total
score will be somewhere around 70% correct,
(63% + 9%=72%).  Rounding to make it easy,
70% of 200 questions = 140. 
Even if you are really smart, you are headed
for a grade right on the border of C and D, if you
skip many classes.
