收到了usyd的conditional offer但是condition如下：You must successfully complete your current studies with the minimum academic requirements for entry to this course. Your GPA will be calculated upon submission of your final official transcript. If your final GPA does not meet the requirement for this course, you may be considered for entry to a lower-level course, depending on availability in your area of study, otherwise your offer will be withdrawn. Please provide all pages of your final official academic transcript including the legend (or grading system) as well as confirmation of degree completion/testamur. The academic transcript should show all the subjects you have studied and the marks/grades you have achieved. If your University has enabled secure electronic transcript services, you must provide the transcript with an electronic certification feature. All documents not issued in English require an official English translation。请问这个是什么意思？是我gpa不够吗？大四了也没什么机会提升gpa了怎么办呢？
