After the GRE, there is an option of sending the test scores to 4 schools without paying any fee.
I had taken GRE before, and I have sent those scores to 4 schools previously. However, I am planning to take the test again, and I wanted to know if I can send the new test scores to the same 4 schools.
If I do this, which scores would those schools select? Also, how can I know if those schools received the new scores?
Additionally, it would be great if someone explains how does the schools know that the GRE scores sent belongs to a particular person.
