I was contacted by an alumnus about a month ago. She asked me to email her a paragraph about something that I did not get to express elsewhere in my application. I still have not emailed her; is it too late now? Should I send it anyway?
Only one way to find out - send it. What do you have to lose? At the very least, you can use the opportunity to find out more about the school.
She probably wanted to know that information to write up a report for Cornell but the deadline for those reports passed.
The deadline was the 15th according to my interviewer.
