Hi
PiyushssjETS mentions that:It takes approximately 5 business days to process requests to send GRE scores to your designated institutions.
GMAC mentions that:Official Score Reports are available to the test taker and his or her designated score-report recipients (schools) approximately three to five days after the test date. When test takers select your program, their scores will be sent automatically to the chosen school(s) and can be uploaded to the candidate’s database.
Based on above timelines, if you feel that it’s getting delayed to verify the scores then you can reach out to AdCom Team.
But please keep give few days AdCom team as buffer as well they would be processing a lot of applications.
