Grading Guidelines

The following guidelines are provided to inform you of your TA's expectations when grading homework assignments:

1) For word problems, first explain how to set up the problem - interpret the given data to form equations or draw diagrams. Show your thinking process with a few sentences if that makes your solution clearer. If you don't do this but magically arrive at the correct answer, you might have a lot more explaining to do later on....

2) Use descriptive equations when starting your solution. For example, look at the following equation:
P[ Network works] = P[at least 2 links work] = 1 - P[no link works] - P[only 1 link works]
The equation set up shown above is precise and doesn't need any further explanation. Use a similar model when possible.

3) Present your solutions neatly and systematically. If your work is unorganized or hard to read, your TA will not be inclined to give you full credit.

4) Try not to skip steps. If a calculator was used, make sure you mention it.

Your grade will reflect how well the above guidelines were followed. If you have any questions/concerns about the grade you received on an assignment, please feel free to contact your TA.
