CONGRATS! Accepting an offer before April 30 is not the same as committing to the school--you can choose to withdraw by April 30 and get your deposit back should you get accepted to your state school. Paying the deposit just guarantees you a seat for the incoming class.
When you sent your update letter, did you get a response acknowledging that your update would be added to your file? (I was placed on HFS and sent an update but didn't receive any kind of confirmation)
Thanks so much!!!!
Yes, I received an email response 3ish days after I sent it confirming that it will be added to my file. You should call them to confirm with them! Good luck and thanks again!!!!
