A reasonable and appropriate examination paper depends on whether the students' marks can conform to the normal distribution in mathematical statistics and it should have four qualities_validity, reliability, discrimination and value of difficulty. By applying normal testing methods to two different examination papers in this essay, the author obtains the following results: Paper One tallies with normal distribution, indicating that the paper is more reasonable and objective; Paper Two is in the shape of negative skewness and lepmokurtic distribution, showing that the paper is easier than the required and less reasonable. This method thereby provides a convincing basis for the improvement on our future English teaching.
