Hey Abhinay,
320 is really a nice score and in a week - WOW! Having said that, you are targeting R2, which is a very competitive round.
For Kelley, I can say that they got 140% more apps for R1. I applied for the same as well but got dinged. And as you said that retake will not be possible because of the deadlines, there is no harm in applying. I have seen one with less than my score in Foster while I got WL.
Also, it will also depend on your profile and the stories you tell. The school also thinks this way: Will we be able to place this applicant based on his goals? I think WashU, Owen, Rice will be great. Go for them.
Feel free to ask any other questions.
Regards,
R
