A student writes:

```     Dr. Patt,
I was hoping that it would not be necessary to waste your time (and
mine) with this, but it has gotten ridiculous and I think that you
should know. There have been grading mistakes on all 3 of the 3 problems
sets that I have received back. I have talked to a couple of other
students who have also experienced problems with the grading on their
problem sets.

Problem set 1b - Problem 2 part c was marked wrong although I had
clearly written that the answer was + infinity.

Problem set 2 - Problem 4 was left ungraded and I did not receive any
points for it.

Problem set 3 - On problem 1 part f, I wrote down the gates for the
following equation
Y[2] = A[1] A[0]' B[1] + A[1] A[0] B[1] B[0]'
which, as I would imagine that any EE grader should know, is equivalent
(according to Boolean algebra) to
Y[2] = A[1] A[0]' B[1] B[0]' + A[1] A[0]' B[1] B[0] + A[1] A[0] B[1] B[0]'

I know that grading is a tedious and thankless job that, much like
umpiring or refereeing, at best goes unnoticed and unappreciated.
However, it is a little bit frustrating when I have to take time to get
each of these mistakes corrected.

Let me also take this opportunity to tell you that, on a more positive
note, I am enjoying the class immensely. Thanks for your time.

I decided to share this with all of you since there may be others with this problem, and I want to be sure you all understand what is going on, and that you know what to do if you find something has been graded incorrectly.

I am sympathetic to the student's complaint. I would also be upset if I received back homework, a programming assignment, or an exam where I was graded incorrectly. But, I think it is important to put the whole thing in context, which I will try to do.
