Hey Shivangi,
Welcome to the club! Also congratulations on your score. Q170! Nice
I had a similar score in both exams when I applied, however, I was planning to go for MBA. Also with 325, I got into UNC.
You should be good with using both the scores. However, some schools permit that you submit both scores. That being said, your Q170 will surely be a cherry on top and when it gets converted to the equivalent GMAT, it becomes 710 so your GRE score should be the one to go for. (IMO
) You should also ask the adcoms in their coffee chats for clarification.
Let me know if I can help you further.
Regards,
R
