I understand every student wants a good grade, and I am also glad to give high ones, but I cannot due to the policy of our school and department and the function of grading itself. The following are some points I believe important for you to interpret your final grade:
1. The final exam weighs 35% because it is the only close-book test we have ever had. I believe its result should reflect some real facts and actually did do so as I expected.
2. The original scores of the final exam ranges from 10+ to almost 70, so I adjusted them by using the formula - (ORIG*1.3)+13. Why I used 1.3 and 13, and a linear function? Because the highest original score becomes 100 in this way. I did not use some complex distribution to curve the scores as Excel does not support this and I don't want to bother to do it myself. I believe most people also prefer the linear transformation since it will put most people beyond the average score rather than the exact 50% when normal distribution is used instead.
3. According to the school's policy, only A-F without + and - are valid for grading. However I would rather to use A+/- and B+/- to show the slight differences, though A+, A, and A- will all be converted to A by our school for example.
4. Finally, I'd like to say that honesty is one of the most important
virtues for a person who lives in the society.
