I recently got into my dream school and one of the top schools in the world for Physics graduate school. However, I have a summary offense on my record for disorderly conduct from 5 years ago that is in the process of getting expunged. The school is not aware of this, since they did not ask about it on the application. I am aware that a background check is performed upon acceptance of an offer. Is it likely that my summary offense would be grounds for reneging my offer? I need to know before I decline my other offers, just in case I get this offer taken away. Thanks!
