请教在美国申请,国内学校成绩如何送?

Most schools will tell you exactly what they prefer in the application instructions.  For example:

http://www.jonesgsm.rice.edu/jonesgsm/Transcripts_and_Tests.asp?SnID=1271195510#19

The instruction may differ from year to year, I recommend checking the websites yourself, instead of having someone else tell you what to do.
