The table shows a gradebook. Letter grades of A, B, C, and D represent numerical grades of 4, 3, 2, and 1, respectively. Each student’s overall grade was determined by computing the average (arithmetic mean) of their grades on the first paper, the first quiz, the second paper, the second quiz, and the final project, and then rounding to the nearest whole number. If the average is exactly halfway between whole numbers, the grade will be rounded up.

知识点概述
本题主要涉及算术平均数的计算以及四舍五入规则的应用。将字母成绩转换为对应数值后计算平均值，并按规则取整得到最终成绩。解析
1. 先将字母成绩（A = 4，B = 3，C = 2，D = 1）对应转换为数值。 2. 对每个学生的五次成绩（两张试卷、两次测验、一个期末项目）求算术平均值。 3. 根据“若平均值恰好处于两个整数中间，则向上取整”的规则，确定每个学生的最终成绩。
