　　一、期末成绩分数：

　　成绩公布栏

　　日期至: 4/27/10 4:07 P.M.Hide Grades

　　课程: 成绩一览:

　　Physical Sci A+ 102.72%

　　Language Arts2 A+ 102.76%

　　Physical Ed尚未公布

　　Skls for Teens 7-8尚未公布

　　Us Hist/Geog 8A94.91%

　　注：左边的红色字体应该是课程的名称，右边黑色字体是孩子在学校的成绩。

　　二、成绩是如何计算出来的，以8年级物理为例：

　　Physical Sci: Richard B.Period: 1

　　Grade: A+ Score: 102.72% Grade Last Published: 4/27/10 2:29 PM

　　首先是各类考试和作业在成绩中所占的比重和成绩，然后加权后得到孩子的期末成绩。

　　Physical Sci: Richard B. Period: 1

　　Grade: A+ Score: 102.72% Grade Last Published: 4/27/10 2:29 PM

　　首先是各类考试和作业在成绩中所占的比重和成绩，然后加权后得到孩子的期末成绩。

　　Category: Weight: Score:

　　Quiz 小考 15% 120%

　　Test 考试 30%99.1%

　　Homework 作业 10%100.93%

　　Participation 课堂参与 5% 95.56%

　　Lab/Activity 实验20% 95.92%

　　Daily Work 课上作业 5% 100%

　　Classwork 合作作业 10% 114.91%

　　Projects 课件 5% 89%

　　注：左边是各项考试、作业的类型，如小测验、大考、作业等，中间是各类考试或作业在期末总评中所占的比重，右边是孩子各类考试和作业的得分，这样最终得出孩子的期末成绩。如：

　　孩子的成绩=120*15%+99.1*30%+100.93*10%+95.56*5%+95.92*20%+100*5%+114.91*10%+89*5%=102.726

　　孩子的最终成绩是102.726，对照学校的评分标准，得到的成绩是A+
