  (The three ``00'' scores are no-shows).

My plan always is:

A  90% and up
B+ 80 - 90%
B  70 - 80%
C+ 60 - 70%
C  50 - 60%
F  below 50%.

Usually the boundaries end up a little bit, but not much, lower than 
the ones I plan to use. (Say 89%, etc).

Midterm I has a weight of 10%, so in theory even a student with a score 
of 0 can still get an A. That is the theory. As a matter of fact, scores 
in different components tend to be correlated. 
So if your score is low: don't despair, but work as the dickens.
If your score is high: feel good about it, and work as the dickens.
