320+100 is enough...|
For phd, ability to do research is the most important and G/T is the least... Don't waste time to update just 10 more scores. Same for GPA. 91 has no difference as 92, to be honest. It doesn't make any sense.
You have 5 papers (some cooperated with famous profs) in submission and this is a sufficient and strong proof of your ability. Please remember what a prof cares is what you think. You can start your application in normal process and tell profs your ideas behind those papers even they would not be accepted.
Please jump out of trap of college entrance examination. Score doesn't mean everything, okay?
