As you know the student body is 120+. So we have to have some precautions to prevent unnecessary objections. These are the rules:
You are welcome to examine your paper. Actually we prefer if you do so. This is the only way for you to see how we grade your papers.
If you decide to object, do it written. If you are right, you get the point. If not, prepare to loose extra 5 points per unsuccessful objection. Consider this as the cost of processing.
