急求助：申请材料中的Diploma showing grades是指什么？

doisme

我申请达姆的ice，这是材料清单，我有些地方不太明白~~请帮帮忙，我挺急的
1。Certificate of scholastic aptitude (certified copy of original)
2。Translation of 1. if original is in language other than English, French or German

3。Diploma showing grades or a grade-point average, should this not be included in 1.
4。Translation of 3. if original is in language other than English, French or German
5。university entrance examination (if applicable)

请问Diploma showing grades or a grade-point average是高考成绩还是高中毕业考试成绩？如果是高考成绩不是和5有重复？
