急！！求助：Total Cumulative Average Grade 是什么

UCI网申里的，
Grade Point Average (on a 4-point scale):*
[size=-1](Enter the number "0" if not applicable or your school didn't use GPA)

Total Cumulative Average Grade (on an alternate grading scale):
[size=-1](Enter the number "0" if your school used a traditional GPA)
这里面的Total Cumulative Average Grade (on an alternate grading scale)是指百分制的加权平均分么？

Looks right. If you use 4-point scale GPA, fill in the first blank. Otherwise use Total cumulative average grade
