Can I cancel the change in major form?

Hello!

I was recently accepted into Purdue to Chemistry but I didn’t feel as if it was the right major for me and I found out that you could request a change in major after your admittance, so I did so: http://admissions.purdue.edu/change/index.php

However, I failed to realize that doing so would forfeit most of my scholarships and financial aid - so I hurriedly sent an email to admissions to ask them if I could cancel my change request!

I was wondering if they would allow me to cancel my change in major form and allow me to continue pursuing Chemistry? When do you think they will contact me back?

Thank you very much! I’m slightly stressed at the moment…
